Grashof Number

Grashof number is proportional to { (buoyancy force) / (viscous force) } and is used in heat transfer in general and free convection calculations in particular. It is normally defined in one of the following forms :

Where:

beta

=

Coefficient of expansion

delta-T

=

Temperature difference

g

=

Gravitational acceleration

L

=

Characteristic length

mu

=

Viscosity

v

=
