this was a great video and extremely helpful for my university project to evaluate CPU cooling designs. I do have one question;
For the closed loop cooling system, how did you ensure the ‘pump’ outlet fluid temperature change over time ? as the system would increase the fluid temperature with every pass.
if the files for this system was available this would also be very helpful !

Kind Regards,

Hi Andrew,

Since it’s an internal fan definition being used to represent the pump it should automatically take into account the “closed loop” temperature and therefore rise as the fluid heats up. Essentially it is passing through the inlet temperature to the outlet. The temperature parameter you may see on the fan definition is not really a driving parameter in this case.

The fluid may take a very long time to converge to the equilibrium temperature. One way to speed the solution up is to guess at the converged temperature and use that as the initial conditions for the fluid subdomain.

One thing that I’m not sure is mentioned in the video is when using the fan to represent a pump in a fluid other than air, it’s very important to specify the “Reference Density” setting for the fan definition in the engineering database.

Hope this helps!
