Using two different FLUENT versions!

Issa · May 9, 2018, 13:30

Hi,

I have used FLUENT version 14.5 to predict the convective heat transfer coefficients of bricks located in a wind tunnel and I have got certain values. Then when I have used another version of FLUENT which is "18.2", I have got different values of convective heat transfer coefficients. Is this normal? If no, what is the problem then?

Yes it's normal. But how different? I honestly can't keep track anymore of all the tiny under-the-hood changes over the years.

What you should do is load only the data file (without doing any iterations) in v18 and see if the htc changed.

Many thanks Lucky Tran for your reply.

The difference ranges from 1-20% which depends on the location of the brick in the wind tunnel.
