FluidFlow3 Piping Systems analysis and simulation by design. FluidFlow3 is the first and only software for piping system design, calculation and optimisation that supports liquids, gases, slurries, 2-phase, and non-Newtonian fluids. FluidFlow3 is a truly original software program for the complete hydraulic design, network analysis, trouble-shooting and optimisation of piping systems. The solution includes flows, pressures, temperatures and phase states through out your piping networks. FluidFlow3 means efficient and accurate modelling for the design of energy efficient, safe, reliable flow systems that are easy to operate and maintain. A very wide variety of industries depend on FluidFlow3 to successfully model new and existing systems, size pipes, select boosters, controllers and other fluid equipment. All modules have, as standard, the ability to include heat loss/gain from pipes. Temperature change or heat transfer to or from equipment is also included.

FluidFlow3 - Liquid module

Over 1050 pre-defined fluids in the database included as standard. For liquid (incompressible flow) calculations, FluidFlow3 solves the fundamental conservation equations of mass, energy, and momentum. Accurate steady state solutions using Darcy-Weisbach, Continuity and Bernoulli equations. Hazen Williams can be used if required.

Communicate designs by exporting in Html, Word, Pdf and Excel format. FluidFlow3 can model any component (fluid equipment item) you are likely to come across, these include: boosters (positive displacement and centrifugal types), valves (including 3-way), flow controllers, pressure sustainers, pressure reducers, differential pressure controllers, check and non return valves, orifice plates, reducers & expanders, venturi tubes, inline nozzles, filters, packed beds, cyclones, centrifuges, labyrinth seals, pipe coils, relief valves, bursting disks, shell & tube exchangers, plate exchangers, auto-claves, knock-out pots, as well as rigorously modelling junctions (tees, wyes, bends, & crosses). For items not covered by the above you can define your own.

FluidFlow3 - Gas module

As gas flows in any network the pressure, temperature, density, enthalpy, velocity and other physical properties are constantly changing. FluidFlow3 calculations take this fully into account to provide an accurate solution without the need to make simplifying assumptions.

A solution approach often used in the literature is to assume ideal gas laws so that analytical equations for energy, momentum and continuity equations can be derived. Rather than make these simplifying assumptions FluidFlow3 uses a calculation procedure that solves the conservation equations together with an equation of state for small pressure loss increments. This means FluidFlow3 obtains a rigorous solution. Available equations of state are:

Benedict-Webb-Rubin

Peng-Robinson

Lee Kesler The flowsheet is the "visual engine" which allows building, navigation, interpretation and analysis of a pipe system.

FluidFlow3 – Slurry module

Can be used to model settling or non-settling non-Newtonian fluids. Settling slurry calculation methods available are Wilson-Addie-Sellgren-Clift, WASP, and Durand. Non-settling slurry calculations methods depend on rheology data. This can be described as Power Law, Bingham Plastic, Hershel Buckley or Casson.

Simulating the performance of settling slurries is dependant on the solid density, concentration, particle shape and size distribution, as well as the properties of the carrier fluid. Selecting the optimum pipeline velocity is usually the most important factor in the design and operation of slurry systems. Operating with velocities too high wastes energy, while operating with velocities too low can lead to pipeline blockage. Fluids can be mixed on the flowsheet. This allows for gas or liquid mixtures, two phase mixtures or dilution effects in slurries to be considered. The fluids database also allows for pre-mixing of single phase liquid or gases. You can define your own fluids and add them to the database in minutes (http://www.fluidflowinfo.com/Videos/AddSimpleFluid.htm) .

FluidFlow3 - 2-Phase Liquid/Gas module

Can be used to model fixed or changing quality systems, with heat transfer included.

FluidFlow3 can analyse systems where the vapor quality changes with pipe position as

well as two phase flow where the vapor quality is fixed

Calculation methods available are Lockhart-Martinelli, Friedel, Muller Steinberg and Heck,

Drift Flux, Beggs Brill or Chisholm Baroczy.

FluidFlow3 uses a modelling approach for the pressure loss calculation, this is a hybrid between the rigorous and empirical methods. By this, we mean, that we use well known empirical correlations and apply them to a differential pipe length. This allows for a flash calculation, liquid holdup and flow regime to be determined for each segment and acknowledges that the pressure loss per unit length changes as the two phase mixture flows down the pipe. Over 85 fluid equipment items (elements) are available to construct any network. This means FluidFlow3 can be used in any industry or application where fluids need to be moved.

FluidFlow3 – Dynamic Analysis, Scripting module

See how your design operates over a period of time, with different initial conditions, different settings or operating parameters Scripting allows extended time analysis or ‘what-if’ scenarios to be considered.

You can write your own scripts using Basic or Pascal. Scripting is used to look at scenarios such as pump station optimisation, flare stack depressurising, or equipment performance over time. You can call external programs and COM modules from script. This means you can start Excel, export results and plot a chart all from script. Flite Software also offers script writing and scenario help as a service. Please contact us to discuss your dynamic analysis needs.
