Grashof number
The Grashof number is a dimensionless number which approximates the ratio of buoyancy force to the viscous force acting on a fluid. Gr = ( g β (Ts - Tinf) L3 ) / ν2 g gravity β volumetric thermal expansion coefficient Ts source temperature Tinf quiescent temperature L characteristic length ν kinematic viscosity See also Reynolds number, fluid mechanics, buoyancy.
