Dear sir, as you can see in my portfolio, I am an expert in fluid dynamics, having designed CPDs and computer refrigerator systems, apart of many other projects in the field, the last 9 years.
I would like to better understand your needs, first of all fixing the goals of the project, that is, human comfort, temperatures and tolerances, hummidity, homogeneity criteria, energy balance, etc. Then, if necessary, we would optimize the system in order to achieve your objectives.
I use to work with Ansys Fluent and/or StarCCM+, and I can also go to Comsol. Please take into account my offer and contact me to better understand your needs, so I can help you to improve your design.
Best regards, and thank you for your attention.
