Need help in CFX Project
 

Dear Ansys experts,

Need assistance in a Project of Solar PVT.

I am not getting the desired results for the Sheet and Tube Model.

Please see the attachment.

There are 2 domains, fluid domain consisting of hollow tubes passing water and a panel solid domain of copper.

The Boundary conditions are as follows:

Mass inlet normal to boundary of 0.09kg/s at 24 degree celcius

Heated back surface on the panel due to heat flux of 1000 w/m^-2

Convection on other remaining surfaces on the panel with heat trasnfer coefficient of 6.423W/m^-2k^-1 and ambient temperature of 45 degree celcius

The fluid model is with Total energy as heat transfer option and turbulence as k-epsilon with scalable wall function and viscous work term enabled.
Buoyancy option is also activated.

The solid domain has Thermal Energy as heat transfer method.

I am expecting a temperature difference at the inlet and the outlet, currently it is the same at both the locations.

Is my model proper?
