Condensation occurs around 80 PSI. We use an input pressure of 40 psi because we cannot exceed a certain decibel level. That gives us an cold air exit of 28 ft/s and a hot air exit of 33 ft/s.There is three junctions and about a foot of .25" diameter tubing with the cold air exit. I did a rough...

Hello, I can't seem to get the great data when I am running my heat sink model through ANSYS NLT. I feel like I am overlooking something. Is anyone experienced and has some guidance. It is a simple convection problem with a certain amount of watts running through a cooper pipe into a copper heat...

I am currently using a exair vortex system and am having problems with the condensation on the generator. If anyone knows how to get the right fraction so I can get colder air that would be great. As far as what you are saying I have been working on keeping the pressure down and decreasing...

I did a similar problem. The difficulty is understanding control volumes when you are using fluid mechanics and heat transfer together. I eventually used ANSYS AIM to solve my problem because it became to difficult.

the air then proceds out and cools CPU's while they are being tested.

Its a generator that cools air.

Hello, I used the Darcy Friction Factor from the Moody Diagram along with the Reynolds number to find energy losses inside the cold air tubing of our vortex system. My calculations showed that I should decrease transitions, length, diameter, and velocity. I am mainly concerned with the figuring...
