Hi again, I need help. I will continue the simulation now with two IT tools. I think my settings are good but in vain I put the inlet temperature to -20 degrees with minimal cooling. Would anyone look at what I’m ruining? SimScale Login Log in to your SimScale account. SimScale makes …

Hi thanks for the details. Actually, there seems to be quite a difference between the two cases: With an inlet temperature of 20 degrees Celsius: [Run 2] With an inlet temperature of -20 degrees Celsius: [average -20] Best regards, Fillia

Hi Oliver! Is there a specific setting that troubles you? And what exactly are you simulating? Bes regards, Fillia

Hi Fillia, I want to simulate what kind of fan speed and temperature a box placed in a room with IT units can achieve proper cooling. What worries me is that I set the input speed to -20 degrees and so there was no significant change in cooling either. To understand the project. I put a box in an …

Hi! Thank you your answer! Yes i understand but i am wondering why the maximum value is not decreasing. And why not the temperature of IT devices. Best regards, Oliver

Hi again! In both simulations, the walls of the internal parts have an ambient temperature of 50 degrees Celsius, and a heat transfer coefficient of 500 W/(K·m²). So to my understanding, the max temperature depends on these properties, have you tested an alternative setup regarding the wall? Best …

Hello! I tried changing the inlet temperature and it is weird that if I give 20 degrees the internal cooling does not change much. I also tried -20 degrees but it didn’t show as much difference as I would have expected. This is strange to me. This is run2 and -20inlet. SimScale Login L…
