Apologies in the beginning. I am a beginner and my question may look stupid to many. But please answer.
I am simulating a flow over a flat heated plate. The simulation is 2D. The plate is of length 152 cms and is at a temperature is 140 deg C. Please answer the following 1) I have taken the domain as 152x900 cms. It that Okay. 2) Can I use Boussinesq approximation. The far field temperature is 24 degree 3) I need to simulate for a plate inclined at 45degree. I have just made it as a flat horizontal plate and under gravity option put x component as g*sin 45=8.3385 and Y component as -g cos 45=- 5.15025 . Is that Okay. 4) Which turbulence models can I try for this. I mean what do you recommend. 5) In the boundary conditions, I have used wall for one heated plate and given it a constant temperature of 142 degree. Rest I have made all boundaries as pressure outlets with zero gauge pressure. Is that Okay. 6) which scheme is recommended for pressure velocity coupling and spatial discretization. Currently I am running with PISO in pressure velocity coupling and PRESTO in spatial discretization. I did use many combinations. Went through manual and saw the net as well. But I am not getting any results. Please share your knowledge |
