In fluid mechanics (especially fluid thermodynamics), the Grashof number (Gr, after Franz Grashof[lower-alpha 1]) is a dimensionless number which approximates the ratio of the buoyancy to viscous forces acting on a fluid. It frequently arises in the study of situations involving natural convection and is analogous to the Reynolds number (Re).[2]
