Grashoff mach
WebThe Grashof number \(\mathrm{Gr}\) is a dimensionless number in fluid dynamics and heat transfer which approximates the ratio of the buoyancy to viscous force acting on a fluid. It frequently arises in the study of situations involving natural convection.It is named after the German engineer Franz Grashof. \[ \mathrm{Gr_L} = \frac{g \beta (T_s - T_\infty ) … WebB.
