One model for every flow challenge in your pipe network
Use FluidFlow to analyze steady-state pressure drop, pump performance, control valves, compressible gas flow, liquid-solid slurry, non-Newtonian flow, liquid-gas two-phase behavior, and heat-transfer effects across connected pipe networks. Start with the workflow that matches your engineering problem, then test it with your own system data using guided free training or a 14-day free trial.
Parallel and branching flow pipe network pressure drop
Estimate pressure drop across connected pipe networks where flow can split, recombine, and redistribute across branches.
Explore workflowSize pumps and model the fluid system against pump performance curves
Size pumps or review pump performance against system pressure drop and changes in fluid properties, or use it to shortlist and select pumps from different manufacturers.
Explore workflowIdentify cavitation and flashing risks across pumps, valves and pipework
Check operating conditions that can create cavitation and flashing risks across pumps, control valves, and connected pipework.
Explore workflowSize control valves and model performance against system pressure balance
Size control valves and review valve performance against flow, pressure drop, and the connected system balance.
Explore workflowModel real gas and compressible flow networks
Analyze compressible gas pipe networks using real gas equations of state — not simplifying isothermal or adiabatic assumptions — for accurate pressure, density, velocity, and equipment results across the connected model.
Explore workflowModel liquid-solid flow and settling slurry piping and pumping systems
