Hello guys,

I have to simulate flow in a rectangular microchannel in laminar region. I have given a constant heat flux and no slip boundary condition to the wall of the channel. Now I have to find out Nusselt number.

So, how to find out that or how to find out mean wall temperature and bulk mean temperature so by their help I am able to find heat transfer coefficient.

Thanks in advance
