I'm simulating a nozzle with rarefied gas. Its kn number is very large. First order slip and temperature jump must be added. I use Maxwell slip equation to write UDF, but I don't know where UDF should be loaded. I look up the data. The sliding speed can be loaded into the shear stress, so where is the temperature jump loaded? Is it loaded directly into the wall temperature? But my wall temperature is fixed at 300K.
If anyone has a compiled UDF file, can you send me one? Thank you very much.1248385182@qq.com |

Hi,dongjie. I'm working on a slip wall simulation too. I also use Maxwell slip equation to write UDF, and I am trying to define the wall shear stress for the "Specified Shear" in Wall boundary condition. But my calculation results turns out wrong. I want to know if your UDF works well? How do you define the slip boundary in your UDF?
Thanks a lot. |
