Thermal Problem in ANSYS

[vtmike]

Hi,

Is it possible to find the internal temperature of a hollow Steel tube at 200 F filled with air at ambient temperature and figure out how long the internal air temperature will take to reach 200 F without using CFD in ANSYS?

Thanks,
Mike

Nobody? Let me elaborate a bit more. This is an assembly of a Steel pipe closed at both ends with another Steel part enclosed inside the outer pipe. I am only considering the effect of radiation heat transfer. Is it possible to carry out a transient radiation heat transfer analysis from the hot outer pipe to the cooler inner pipe to find out how long it will take to heat up the internal pipe to a specific temp?

Mike,

CFD should only be required if you are needing to simulate convection. For your case I am pretty sure Ansys can do a transient heat transfer involving only radiation, but you might want to include conduction as well because it would be more accurate and would involve only adding a temperature boundary condition. The thermal conductivity for steel and air should already be provided by default for Ansys.

Hope this helps,

Steve
