Exceptional ROI at Competitive Cost

FluidFlow delivers enterprise-grade calculation capability at a fraction of typical software cost. According to CoMo Industrial Engineering, the software saves up to 80% design time — directly translating to labor cost savings on EPC projects.

Intuitive Interface, Easy to Use

FluidFlow is designed so users can start building pipe network models within minutes. Most engineers are up to speed in a few hours. Free basic on-demand training covers software essentials with introductory theory on liquid and gas modules.

Comprehensive Database — 1,200+ Fluids, 800+ Equipment

FluidFlow integrates a database of over 1,200 fluids (including thermodynamic and transport properties) and over 800 fittings, valves, and piping components with built-in resistance data. Users can expand the database with custom fluids and proprietary equipment.

Unrivaled Technical Capabilities for Every Flow Type

From single-phase liquid to non-Newtonian slurry — all in one software, no module switching required

Multi-Flow Simulation — Liquid, Gas, Two-Phase, Slurry

FluidFlow operates with integrated modules (Liquid, Gas, Slurry, Two-Phase) within a single software environment, allowing multi-fluid-type systems in one file. The software automatically detects fluid phase based on operating conditions — no manual module switching required.
  • Liquid (incompressible): Darcy-Weisbach (Colebrook-White), Hazen-Williams, Shell-MIT, fixed friction factor.
  • Gas (real compressible): Peng-Robinson, Benedict-Webb-Rubin, Lee-Kesler equations of state; Joule-Thomson effect; choked flow detection.
  • Two-Phase (liquid-gas): 8 correlations including Beggs-Brill, Friedel, Chisholm-Baroczy, Lockhart-Martinelli, Müller-Steinhagen & Heck, HEM; automatic correlation selection via Whalley Criteria.
  • Slurry & Non-Newtonian: Durand, WASC, WASP, Liu Dezhong, Four Component Model; deposition velocity calculation; pipe inclination corrections.

Automatic Equipment Sizing

FluidFlow automatically sizes key piping system components, reducing manual iteration and helping engineers evaluate alternatives quickly
  • Pipes: Economic velocity (balancing capital and energy costs), standard velocity, or pressure gradient.
  • Pumps: Auto-size based on defined flow or pressure rise requirements.
  • Control valves: Preliminary Cv/Kv calculation with process data for manufacturer model selection.
  • Relief valves & bursting discs: Orifice area calculation per API 520 Part 1.
  • Flow measurement devices: Orifice plates, Venturi tubes, flow nozzles per ISO 5167-1:2003.

Complex Branching Network Analysis

Branched and parallel pipe networks are inherently complex because flow and pressure interact across every connected path. FluidFlow solves complete networks — including branched and parallel paths — to determine flow distribution, pressure profiles, and the system constraints driving real operating behaviour.

Pump Curve Performance Analysis

FluidFlow evaluates how a pump performs within its connected system — showing the operating point in terms of head, flow, efficiency, power, and NPSH. The software finds the pump duty point balanced with system resistance using its performance curve, checks NPSH_available margin over NPSH_required, and identifies potential issues such as excessive head, high velocities, or operation outside the intended range — before pump purchase.

Integrated Heat Transfer Analysis

The heat transfer module is integrated across all calculation modules by default. Temperature changes along the network affect fluid properties at each calculation point
  • Detailed heat loss/gain calculations for insulated piping.
  • Buried pipe heat transfer accounting for soil conductivity and burial depth.
  • Fixed heat transfer rate or fixed temperature change (ΔT) across pipe sections.

CAD & Excel Integration, Custom Reports

FluidFlow supports PCF file import from CAD tools (SmartPlant 3D, CADWorx, SolidWorks, Autodesk) to build models directly from 3D designs. Excel integration reads input data and writes results for batch processing and reporting. Reports are generated in PDF, Word, and Excel with company branding. Pascal/Basic scripting automates repetitive tasks, custom calculation sequences, and user-defined control logic — included free with Liquid or Gas license.

FluidFlow Serves Multiple Industries

Used in every sector where fluids flow through fully filled pipes — from oil & gas to shipbuilding

Oil & Gas

Production facility design, gas gathering, pipeline transport, relief systems, flare headers. FluidFlow simulates real gas behavior (no isothermal or adiabatic assumptions), detects choked flow at restrictions, and sizes relief valves per API 520 Part 1.

Mining & Minerals

Slurry pipelines, tailings transport, dewatering systems, thickener underflow. FluidFlow calculates settling slurry flow using Durand, WASC, WASP, Four Component Model correlations, with pipe inclination corrections and minimum deposition velocity. Slurry pump derating per ANSI 2021 Monosize, GIW 4CM, HI Guidelines.

Chemical & Petrochemical

Process piping, reactor feed systems, cooling water, chemical dosing. FluidFlow simulates both single-phase liquid and two-phase (liquid-gas) flow with automatic phase detection — supporting cavitation evaluation, parallel flow distribution, and control valve performance.

Power Generation

Steam distribution, condensate return, cooling systems, fuel gas supply. FluidFlow simulates real gas flow with Peng-Robinson and BWR equations of state, calculates the Joule-Thomson effect, and detects choked flow at pressure-reducing locations. Per Tecsar, FluidFlow proved a steam header system lacked required capacity — saving approximately $800,000 in capital.

Water & Wastewater

Distribution networks, pumping stations, treatment plant hydraulics, fire protection. FluidFlow calculates single-phase liquid flow using Darcy-Weisbach (Colebrook-White) or Hazen-Williams — suitable for urban water distribution networks and firewater rings. Auto-sizes pipes by standard velocity or pressure gradient.

Shipbuilding & Marine

Ballast systems, fuel oil transfer, fire-fighting mains, seawater cooling. According to Deltamarin, FluidFlow sized all pipelines without pressure reducing valves and balanced flow distribution through nozzles quickly. Cochin Shipyard uses FluidFlow for cooling water, fuel oil, ventilation, and more.

FluidFlow FAQ

FluidFlow is pipe network analysis software for engineers who design, size, troubleshoot, and optimize fluid piping systems. It performs steady-state hydraulic analysis of liquid, gas, two-phase, slurry, and non-Newtonian flows — calculating pressure drop, flow distribution, temperature profiles, and equipment operating points across complete pipe networks.
