QUICK HYDRAULICS - Flowsheet Simulator and Pressure Drops


QUICK HYDRAULICS - Flowsheet Simulator and Pressure Drops
Windows 95/98/NT/2000/ME/XP



Quick Hydraulics offers a low cost alternative for flowsheet simulation, heat and mass balances and pressure drop applications. Quick Hydraulics has a wide range of application in process design. Calculations utilize an integrated component database that includes detailed properties for more than 800 components. User specified distillation curves and pseudo components are handled with a properties generation routine. Heat and mass balances as well as flash calculations are carried out automatically. The user has a choice of thermodynamic options and calculation modules to cater for most process flowsheet simulations.

Heat Exchangers - Use heat exchangers in your flowsheet simulations. Specify the number of tubes, passes etc and get the program to calculate the pressure drops. Checks on heat exchange area are also carried out.

Comprehensive fluid database and estimation technology - Quick Hydraulics contains detailed properties for over 800 components. Users can add distillation curves, pseudo components and user defined components. Equations of state include Ideal, Soave Redlich Kwong, Peng Robinson, Chao Seader and Grayson Streed. Fluids include: supercritical and other common gases, water, paraffins, olefins, dienes, naphthalenes and aromatics, sulphur containing organics, halogen containing organics, nitrogen containing organics, alcohols and phenolics, ketones and aldehydes, esters, ethers, organic acids, oxygen containing organics, inorganic acids and inorganic halogen components.

Pumps and Piping - Pipe calculations can be done as single or two phase flow, with or without heat loss. Pipe fittings, insulation and elevation changes are taken into account. Fittings can be combined to simulate manifolds based on database or user supplied resistance coefficients. Pump simulation with differential heads, discharge pressure and power is performed. User supplied pump curves can be entered.

Range of simulation modules - Flowsheet simulation is performed by graphically connecting process equipment modules. Hydraulics systems are drawn using flowsheets. The simulation modules include:

Piping, elbows and tees, reducers, valves (gate, globe, butterfly, plug), check valves, pumps, heating/cooling coils, compressors/expanders, vertical and horizontal vessels (gravity settlers), axial and radial flow packed beds, shell and tube heat exchangers, air cooler heat exchangers, fired tubular heaters, restriction orifices, relief valves, control valves, strainers, steam traps, stream modifiers, stream splitters (including flashing) and component splitters.

Piping Systems FluidFlow3 - Design and Simulation Software

Piping Systems FluidFlow3 - Design and Simulation Software



A truly original software program for the design and optimization of pipe networks, transporting compressible, incompressible, gas-liquid two phase, settling slurries or non-Newtonian fluids.
The efficient and accurate modelling of your networks is essential for the design of energy efficient, safe, reliable flow systems that are easy to operate and maintain.
This product is used successfully in many diverse industries to model new and existing systems, size pipes, select boosters, controllers and other fluid equipment.
Please take a few minutes to discover why we are best in class.
The tools within FluidFlow3 enable you to:


Heat transfer capabilities are included as standard within FluidFlow. At each network element you can select from any of 3 heat transfer options (pipes have 4 options):

  • Ignore Heat Loss/Gain
  • Fixed Temperature Change
  • Fixed Transfer Rate
  • Do Heat Transfer Calculation

For pipes, the software can also calculate heat loss/gain from the pipe. Pipes can be insulated with different types of materials using any thickness. Convection, conduction and radiation losses are calculated. This means you can use FluidFlow to optimize energy use by selecting the economic insulation thickness.

FluidFlow can model shell and tube exchangers, plate exchangers, coils and autoclaves.




















The example opposite shows the heat loss from a 1 kilometer length of uninsulated pipe.


There are over 300 QA example calculations made before each release of FluidFlow. This is one of the verification heat transfer calculation examples.





An example circuit showing 2 heat exchangers with full modelling of both the shell and tubeside. Usually modelling of one side is sufficient.

Several Pressure Loss correlations can be used including: Deleware method, using manufacturers loss data, or using a fixed pressure loss.

With the 2-phase module you can also consider condensors and evaporators.




This network, shows how FluidFlow is used by a customer to model a chilled water cooling system in a Data Centre. Modelling of what happens due to pump failures is also considered in this model.

We have many other customers who model chiller circuits and/or district heating circuits using FluidFlow.

One customer has sucessfully modelled the chiller system for Heathrow Airport and another the storage tank heating system at Europoort. Both networks contain over 5000 pipes and node and solve in a few minutes.

Overview

HYDROFLO 2.1 is a powerful software tool that assists piping system designers in the modeling and analysis of single source/single discharge, re-circulating and gravity flow piping systems. These systems are commonly found in industrial process, water supply, wastewater treatment, fire protection, chemical process, mine de-watering, irrigation and HVAC applications among others. The models created with HYDROFLO can consist of up to 10 parallels and hundreds of elements (pipes, valves, fittings, pumps and tanks). Virtually any type of system element can be described from the wide variety of available elements available on HYDROFLO's menus. Element head losses can be described using flow vs. head loss curves, fixed head loss curves and custom friction coefficients.
HYDROFLO models systems conveying any type of incompressible fluid and solves for the full-pipe, steady-state pressures and flows. Hydraulic grade line plots are displayed in the workspace of solved systems so that suction and high-head conditions are easily observed. The Hazen-Williams equation is available for use with water systems and the Darcy-Weisbach equation is available for use with any type of incompressible fluid. Once a system's total dynamic head and flow are found, PumpBase™ can be used to find the best pump for your application.
Systems are built by dragging and dropping both individual or groups of elements onto the workspace. HYDROFLO's new clipboard is available for mass storage, moving and copying of elements. The clipboard can be saved separately from project data, so that a collection of pumps and/or other elements can be brought into any design.Fly-over element inspection (placing the mouse cursor over elements) lets you rapidly identify system components. Elements can be stretched and/or increased in image size for easier viewing. Eleven example problems with their data files are presented in the Help file that depict most of the possible situations that arise in system design.
Once a system is built, PDF reports of flows, pressures, line and pump graphics and other operational results can be previewed and printed. Individual or groups of elements can be edited using the new Group Editor. Elements can be "tagged" to assist with editing.

HYDROFLO Pump PlotMany types of hydraulic problems can be solved...

  • Validation/calibration of existing single source/discharge systems.
  • Modeling a proposed system’s operation.
  • Determination of line head losses at a specific flow rate (termed a forced-flow system).
  • Analysis of cavitation (Net Positive Suction Head) problems.
  • Comparison of equivalent SI unit to English unit designs.
  • Modeling of re-circulating and gravity (non-pumped) flow systems.

CONVAL® - the PC software for engineers, planners and operators of industrial plants.

CONVAL® integrates extensive calculation functionalities for components and processes in industrial systems, based on tried-and-tested methods, such as DIN, VDI, VDMA EN/ISO and ISA.

By strictly avoiding all forms of dependence on equipment manufacturers, CONVAL® guarantees flexible, professional working.
The range of available calculations extends from control valves and throttle elements through piping systems to heat exchangers, including integrated property calculations (based on a property database) and comprehensive databases for control valves, safety valves, materials, etc. as standard.



The current release of CONVAL® is 8.0

Supportinformations for older CONVAL® versions can still
be found in the support area for CONVAL® 7.0CONVAL® 6.0 andCONVAL® 5.0.


CONVAL® can calculate pressure and temperature-dependent properties according to various methods.
Almost all the program modules require a certain amount of information about the pressure and temperature-dependent properties of the medium being used in the process.
CONVAL® is capable of calculating this process data automatically for a large number of media (approx. 1000) in connection with the calculation program.
Three different calculation methods for process data are offered at present, namely:
  1. Using approximation equations based on a property database for physical constants.
  2. By interpolation on the basis of a property database for actual measurement series.
  3. With the help of extremely accurate thermodynamic equations of state.
  

Approximation is a very useful option if no special calculation methods, such as the steam table (IAPWS 97) for water, are available.
CONVAL® integrates an extensible property database containing around 800 substances and their physical constants, which can be taken as a basis for pressure and temperature-dependent calculations of the substance properties.
The boiling pressure pv of a liquid can be calculated, for example, in its state at a temperature t1, or the boiling temperature tv of this liquid in its state at a pressure p1, in accordance with Riedel's correlation (error < 10%).
Alternatively, it is possible to calculate the real gas factors Z1 and Zn, and thus also the specific gas densities. This calculation is based on Newton and Raphson's correlations and on publications by Dranchuk, Purvis, Robinson and Takacs.
The operating density of liquids is calculated with the help of the physical constants stored in the database according to mathematical approximation methods described by R. W. Hankinson and G. H. Thomson. In conjunction with other authors these methods are also referred to as the COSTALD correlation. The error is < 1% for the majority of applications and only exceeds 5% under a very limited number of boundary conditions.
Approximation methods are also available for calculating the isentropic exponent, the sound velocity, etc.
