natural convection flow inside a triangular

Ehsan Khalili · March 27, 2011, 04:22

Hi guys
I am trying to simulate a natural convection flow inside a triangular..... by fluent. I have read tutorial 5 but now i am confused how i can increase Rayleigh number in fluent.
Thanks for your help

Hi, Ehsan,
You can change the variables in the definition formula.

Hi
I have to change the Rayliegh number from 50 to 10000. If i change temprature, another variables will change little. In what way the Rayliegh number could be changed into lower number.
Best regards
