Grashof number

In fluid mechanics (especially fluid thermodynamics), the Grashof number ( $Gr$ , after Franz Grashof^[a]) 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]
