Cooling plates and Fan Curve
 

I am relatively new to Star CCM+ and have a question regarding Cooling plates using a fan. The problem construction goes like this.There is a heat flux that is being given from the top side of the plate , while the air enters through annular regions from the left side of the plate due to a fan that is kept on the other side(suction pressure).

The issue here is that I do not have a Boundary condition at either ends of the plate and I only have the fan curves associated with the fan(not the tables, but the curves from the manufacturer's manual).

Can someone tell me how I can understand the Mass flow rate or the suction pressure from the fan curves(for one BC) and how to simulate ambient pressure and temperature at the other Boundary condition. I have also attached the fan curve with this file. It would be of great help. Thanks in advance.

If you solve for the flow by specifying different suction pressures and then calculating the resulting CFM, or running with different CFMs and calculating the required suction pressure, you will get another curve called the system curve. For example, you perform three runs at 50, 100, and 150 CFM and calculate the pressure drops associated with them, let's say 0.3, 0.7, and 1.6 inches of water. You can plot these points on your fan curve and connect them using a smooth curve. Now that you have the system curve, find the intersection of system curve and pump curve. That is the system operating point, and it will tell you what is the operating flow rate or pressure drop through the system.

For the boundary conditions, you can either find appropriate heat transfer coefficients from literature, or (this is the better option imho) use a conjugate heat transfer simulation, and let the software calculate the heat transfer rates for you.
