Property variation with temperature

December 14, 2000, 07:45

I am using density as a function of temperature. I am using 2D segregated solver. My Mach no. is 0.1 only. Does fluent 5.3 solve the following eqn for continuity in 2D steady state?

dou(Ro*u)/dou(x) + dou(R0*v)/dou(y) =0

or does it solve only the following for the above mentioned case ?

dou(u)/dou(x) + dou(v)/dou(y) =0

I would also like to know for the above mentioned case, with RSM , is Fluent5.3 using favre averaging or reynolds averaging only?.

Any help will be useful. Thanks..

1. d(Ro*u)/d(x) + d(R0*v)/d(y) =0

2. Reynolds averaging only.
