time step for unsteady film cooling simulation -- CFD Online Discussion Forums

December 11, 2007, 07:14	time step for unsteady film cooling simulation	#1
Janendra Telisinghe Guest Posts: n/a	Hi, I'm trying to simulate film cooling on a flat plate using an unsteady solver. I'm not sure what time step I should use for the simulation. My freestream flow is M=0.3 whilst the plenum flow is M~=0. I wondered whether anyone could advice me on how to determine the time step for the unsteady simulation please? Many thanks From JT
