文摘

Compressible and incompressible solvers are compared on a multi-orifice nozzle. Compressible solution shows a wide variation of fuel properties along the nozzle. Compressible solver is up to 5% more accurate in stationary mass flow prediction. Momentum flux and outlet velocity are also better captured with compressible flow.
