FluidFlow Software

CEPL is pleased to announce that we are the sole-distributor of the FluidFlow software in India and the Middle East.

FluidFlow is a powerful tool that allows you to model the fluid behaviour within complex piping systems and accurately predicts how the system will work for a given set of boundary conditions. The software uses a number of well-established models and correlations to solve the piping systems and boasts a comprehensive database of fluids, pumps, valves, pipes, and other components.

FluidFlow is a modular software product meaning you can choose the calculation modules which are relevant to your company and industry. You can therefore model and fluid type or phase state within one single model. This means you don’t have to purchase or learn how to use multiple software programs and spend extra time creating multiple models in separate programs to complete your design analysis.

FluidFlow Modules

1. Liquid Calculation Module

This module is used by engineers to calculate operating pressures, pressure losses, and flow distribution in liquid piping transportation systems. FluidFlow can model any component that a user is likely to come across. Users can choose from three pipe pressure loss models; Moody (Darcy-Weisbach), Hazen Williams or Fixed Friction Factor (Darcy) The module includes a powerful equipment sizing functionality while also allowing you to model vendor pumps in your systems and considers changes in pump speed and impeller diameter. FluidFlow automatically creates the system resistance curve for all pipes in your piping system. The liquid module can be used to model a wide range of systems such as cooling water plant, district heating mains, liquid nitrogen plant, LNG plant, mine dewatering systems, fire protection systems, utility systems, etc.

2. Gas Calculation Module

Design of gas pipe flow systems can often present complex challenges which can be overcome with the help of FluidFlow which takes into account the pressure, temperature, density, enthalpy, velocity and other physical properties that are constantly changing in a piping network in which a gas is flowing. Users can choose from the available equations of state; Benedict-Webb-Rubin, Peng-Robinson, Lee Kesler. The software automatically detects choked flow conditions as well as taking into account the Joule-Thomson effect.

3. Two-Phase (Liquid-Gas) Calculation Module

FluidFlow can be used to calculate pressure losses and flow distribution in two-phase pipe flow systems which can often be quite complex. The software can be used to model fixed or changing vapor quality systems with heat transfer included. Calculation methods include Lockhart-Martinelli, Friedel, Muller Steinberg and Heck, Drift Flux, Beggs Brill, and Crisholm Baroczy. FluidFlow uses a modelling approach for pressure loss calculation which is a hybrid between the rigorous and empirical methods. Flow pattern maps are automatically generated by the software for each pipe in your system

4. Slurry Module (Non-Newtonian, Non-Settling Slurries, Settling Slurries and Pulp & Paper Stock Flow Systems).

This module can be used to model settling or non-settling non-newtonian fluids as well as Pulp & Paper Stock Flow Systems. Settling slurry calculation methods include Durand, Wilson-Addie-Sellgren-Clift (WASC), WASP, Liu Dezhong and the Four Component Model. Non-settling slurry calculations methods depend on rheology data which can be described as Power Law, Bingham Plastic, Hershel Buckley or Casson. Pulp & paper stock loss correlations include TAPPI & Moller K. FluidFlow allows users to study dilution effects in slurries.

5. Scripting Module (Dynamic Analysis)

The scripting module allows users to perform a wide range of dynamic simulations such as the study of tank fill/drain times based on a set of design pump operating conditions, analyze system pressure as demands vary, investigate system control philosophies, evaluate valve performance for variable speed pumps, flare stack depressurisation, analyze scale build-up in systems and study the effect on flow rate, optimize pump and system performance. You can write your own scripts using Basic or Pascal.
