Dear all

I wish to solve a 1D heat conduction problem inside a copper block.

the bottom end has constant heat flux boundary condition and the top end has a variable heat transfer coefficient.

i have measurement data for transient temperature profile at two interior points.

How do i estimate the transient heat transfer coefficient?

I understand there is no direct option available in fluent.but even if I am supposed to write UDF what is the approach and how to go about the same?

other wise are there any open source codes available for solving inverse problems?

regards
Siva

Hi,

i have the same doubt as you. Take a look at Inverse and Transient Heat Transfer Problem on commercial software: is it possible? .
