I am considering study of rotating disc with shaft (3000RPM) in which, on surface circular strip of certain depth the internal heat is generated, for around 900 seconds is applied. Now, in order to reduce computational cost/time, its been reduced to 2D axisymmetric.
1. In this case will heat generation application be Q/2 or the same?
2. If disc and shaft is stationary and other conditions are same as above would it change internal heat generation application in 2D?
3. How ANSYS software makes the numerical calculation for which results are finally 3D by revolving around axis?
Thanks in advance.
A 2D axisymmetric analysis in fact is a full 3D analysis for structures having a symmetry of revolution and subjected to axisymmetric loads. I understand that you want to apply a heat flux Q at the boundary. If this flux (defined in w/m2) is applied on the surface of the element of the 3D model, the same value must be applied on the boundary of the 2D-axisymmetric model. The same remark holds for question 2 but I am not sure to understand your question.
