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. Usually the density decreases due to an increase in temperature and … See more The first step to deriving the Grashof number is manipulating the volume expansion coefficient, $${\displaystyle \mathrm {\beta } }$$ as … See more • Cengel, Yunus A.
