simulate a cht problem
 

hello everybody,

i hope somebody can help me with my problem. i have only a plate (material is aluminium) with a temperature of 60°C. i want to simulate the heat flux in the air in the case of free convetion. the stream should be laminar. the air is 20°C warm. the plate has the dimensons of 0,5m length and 0,5m width. how can i realize this problem with star_cd. if the problem is unclear don't hesitate to ask me questions.

chris

Try to chek tutorials of star-cd. You can find all answers here.

For this star-ccm+ is recommended. You can download it from the support website and it uses the same license. You can define the interface aluminium and air easily. How come you were recommended star-cd for your type of study?

Hi Chris. Assign cell type: Solid for the plate Fluid for the environment Then assign to the plate a wall boundary condition in which you enforce an heat flux (60 - 20)* 15 = 600 W/m^2 You can change the coefficient in a range of 0 - 15. That's all
