The Grashof number is: G r L = g β ( T s − T ∞ ) L 3 ν 2 {\displaystyle \mathrm {Gr} _ {L}= {\frac {g\beta (T_ {s}-T_ {\infty })L^ {3}} {\nu ^ {2}}}\,} for vertical flat plates. G r D = g β ( T s − T ∞ ) D 3 ν 2 {\displaystyle \mathrm {Gr} _ {D}= {\frac {g\beta (T_ {s}-T_ {\infty })D^ {3}} {\nu ^ {2}}}\,} for pipes. 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 … 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. Using slope of the linear regression line … 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. The $${\displaystyle v}$$ in the equation above, which represents specific volume, is not the same as the See more • Cengel, Yunus A. (2003). Heat and Mass Transfer: A Practical Approach (3rd ed.).
