Can ANSYS AIM Solve Complex Cooling Fan Calculations?

AI Thread Summary
The speed of a cooling fan significantly impacts air flow, which in turn affects heat removal from a heat source. Calculating this relationship involves understanding heat exchanger and heat transfer principles, influenced by various factors like geometry and surface characteristics. A steady-state temperature can be determined given specific heat generation and air flow rates. The discussion highlights the complexity of integrating fluid mechanics with heat transfer calculations. ANSYS AIM is suggested as a useful tool for solving these intricate problems effectively.

Hi everyone!
I was wondering if there is a known equation to calculate how the speed of a fan affects the cooling of a heat source. Is there a way to calculate this or know what type of relationship it is?
Thanks!

The speed of the fan will affect the air flow through the fan. The air flow in turn will affect the heat removed from the source. The exact details depend upon the geometry, the surface of the hot body, and a host of other variables.

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.
 

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
