Hi all,
Im trying to simulate a gas turbine combustor for which I know inlet conditions (massflow, pressure, temperature) and I want to evaluate efficiency of the combustor based on the outlet conditions. I have experienced that OF blows up whenever I specify at the inlet (fixedValue BC) either: a) temperature pressure and velocity (T p U - fixedValue) b) pressure and massflow (p phi - fixedValue) c) pressure and velocity (p U - fixedValue) The other quantities are set to zeroGradient (note for velocity also used pressureInletVelocity). FYI, im using reactingFoam which uses PISO solver for momentum equations. This is a simulation for my master thesis, so I really need your precious help. Any suggestions? Thx |
