rotating disk
 
Hello, I'm simulating a rotating disk in the air but my simulation doesn't correspond to the experimental measurements. I've already meshed the disk and the control volume, and the mesh quality is about 0.3 and there aren't bad cells. Within this velocity, the temperature around the disk is about 100°C by experiment but during my simulation the temperature is only at 50°C. The aim of this simulation is to determine the moment at the axis. Now, I try to change the fluid (air) into ideal gas and change the options for the density and viscosity.

Could someone give me some advice about really important parameter ? What is really the consequence of the turbulent viscosity option in fluent?

Disk specification: Radius 95 mm; thickness 2 mm; roughness 5 micrometer, frequency 0-500 Hz

Model: k-epsilon RNG; coupled; energy

Best regards

David

I think that fluent is a powerful soft.... damage that it's difficult to use it. there are some people very good and some also very bad . Dammage for you !

you can go to bed.
