I am doing Jet impingement heat transfer phenomenon on a solid plate in 2D. Solid plate is at 500K initially. Now from air jet impingement, it will cool down the Solid target plate.
I am initializing solid plate using patch option. I am running steady sate phenomenon. The problem here is I am not able to observe temperature variations in solid domain. However there is temperature variation along interface in fluid region only. I need to see temperature variation in solid plate to do structural analysis. Interface is automatically selected as "Coupled" for both wall and its shadow. Please help. |

If you have steady state problem, your solution will not depend on your initializing. You can initialize what you want, the solution depends only on your boundary conditions.

Ty sir, I have solved the problem for this convection using transient solution. Now I need to apply CHF boiling model for because of film boiling on solid surface. Please suggest me the further approach as everytime I run my solution, errors do appear.
Its a 3 phase flow. In fluid domain air is there, Water will come from inlet, further as water fall on solid, film boiling occurs and vapors are form (3 phases : air, water and vapor). Now I am making assumption that air is same as vapor and reducing the problem to 2 phase flow. Now, Vapor is there is entire fluid domain and water enters from inlet. As water falls on heated solid, film boiling occurs and vapors are formed. I am using by default boiling conditions (saturation temp = 373K) and setting my residual monitor when water facet maximum temperature reaches 373K (as boiling will stop at this condition). Please help. |

Sorry, I'm not an expert in multi phase flows.
