Impinging Jet Modeling Problem
I am trying to model an impinging jet . There is a nozzle through which air is exiting vertically downwards and hitting the ground. I have two questions about it.
1) what would be the top boundary condition besides (next to) the inlet? Is it pressure or Inlet with zero U and V velocities? If I put Inlet condition bc there with zero U and V , then what values do I put for k and epsilon there ?
2) What are the values of inlet turbulent kinetic energies and dissipation which I need to specify for the inlet jet using k-epsilon model? I am using both FLUENT and STARCD for analysis.
Re: Impinging Jet Modeling Problem
A)Start with inlet velocity magnitude (along one flow direction only), in other directions put zero. B) Put k=10, e=10 C) Solve it D) Validate and verify before proceeding with further complex problems. By the way, what is the jet velocity u r using ?
