Transient Incompressible Flow Simulation Software
AFT Impulse is a powerful fluid dynamic simulation tool used to calculate pressure transients in piping systems caused by waterhammer. Designed for use in liquid systems containing water, petroleum and refined products, chemical products, cryogens, refrigerants, and more, AFT Impulse is an essential tool with the ability to tackle your most demanding systems.
How does it work?
AFT Impulse incorporates a steady-state solver providing seamless transfer of initial conditions to the transient analysis. Steady-state solutions are determined using Newton-Raphson matrix iteration. The traditional Method of Characteristics is used to solve the transient mass and momentum equations of pipe flow.
