hi

does anyone know how to input (or change) richardson number in fluent ?

my model is two phase mixed convection nanofluid.

mixture model (water+AL2O3)

there is no where that you can write down the richardson number you wish to work on fluent.

richardson number come from Gr/Re^2 (if you dont know what these are then find a heat transfer book or google it)

you can calculate the current richardson number of your model by velocity, temperature etc...

and if you want to change it then you need to change those values accordingly.
