The link … Buckingham π theorem Another form of dimensional analysis that will result in the Grashof number is known as the Buckingham π theorem . This method takes into account the buoyancy force per unit volume, F b {\displaystyle F_{b}} due to the density difference in the boundary layer and the bulk fluid. See more 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 See more The Rayleigh number, shown below, is a dimensionless number that characterizes convection problems in heat transfer. A critical value exists for the Rayleigh number, … See more In a recent research carried out on the effects of Grashof number on the flow of different fluids driven by convection over various surfaces. … 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 causes the fluid to rise. This motion is … See more The first step to deriving the Grashof number is manipulating the volume expansion coefficient, $${\displaystyle \mathrm {\beta } }$$ as follows.
