boussinesq approximation
 
DEAR FRIEND, my project is on opposed bouyancy flow over a SQUARE cylinder .THE FLUID IS AIR . i am using boussinesq approximation in my problem.when i choose boussinesq approximation in the drop down list of material panel, a constant value of density is required. i wanted to know what constant value of density should i give in the material panel.should it be 1.225 OR CAN I GIVE ANY ARBITRARY VALUE. I WILLL BE EAGERLY WAITING FOR YOUR VALUABLE REPLY...

THANKS

HI,

Boussinesq approximation needs constant value of density, of fluid under study.as your fluid is air. use density of air.
