Pressure-Inlet Boundary Condition
Hi Guys,
Considering a natural Convection problem (Steady State, Pressure-Based).I wonder if anyone knows what is the best value of the following factors in Pressure-Inlet Boundary Condition for Air at 20° C in a box with ∆T = 10° C ( T top –T bottom) at. • Turbulent Intensity • Turbulent Viscosity Ratio OR What is best value for K and Ɛ ? Cheers, |

of course ,it takes many time to verify! |
It does not have to be exact. You can also use the option of intensity and hydraulic diameter.
For intensity you can mention 5% for the not highly turbulent flow (guess on the basis of upstrem condition of flow domain) and 10% for highly turbulent flow. You can easily compute the hydraulic diameter based from the geometry features, |
Thanks So much guys, your solotions:) are reaseonble and worked for me
