WebApr 6, 2024 · Grashof number, Gr, is the ratio between the buoyancy force and the viscous force: G r = g β ( T s − T ∞) L c 3 ν 2 Nusselt number is a function of the Grashof number and the Prandtl number alone. Nu = f (Gr, Pr) Important Non-dimensional numbers: Biot number → Ratio of internal thermal resistance to boundary layer thermal resistance In fluid mechanics (especially fluid thermodynamics), the Grashof number (Gr, after Franz Grashof ) 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 … See more Heat transfer Free convection is caused by a change in density of a fluid due to a temperature change or gradient.
