It's a hollow cylinder having inner and outer radius a & b respectively.At the inner surface there is a heat source which is generating heat at a rate of 10^5 W/m2.The outer surface is dissipating heat into a fluid(having temp 100C) by convection.Convective heat transfer coefficient is h=400 W/(m2*C).I need to determine inner and outer surfaces temp.Need help applying Convective heat transfer coefficient is h=400 as boundary condition.
Thanks,

Hi,
It sounds like you need a surface heat flux on the internal surface and a film coefficient on the outer?
Hi,
Looking at your first post, would it not be 400 W/m2/K at 100C?
Thanks,
Jon
Hi,
As far as I know,it will be W/(m2*C) or W/(m2*K).
Thanks for your reply.

Hi Sabbir!!!
You should apply a film co-efficient boundary condition to the outer surface of the cylinder. A heat generation BC in the inner surface of the cylinder. Only then you can measure your required outer surface temperature at steady state or transient state 🙂
Thank You!
If you know what the total area of the inner cylinder is, couldn't you calculate the total heat generation (i.e., W/m^2 * m^2). There is an option to select total heat generation as a BC.
