Web1.2 Buckingham Pi Theorem; ... But, in natural convection the Grashof Number is the dimensionless parameter that governs the fluid flow. Using the energy equation and the buoyant force combined with dimensional analysis provides two different ways to derive the Grashof Number.
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 ) … david whatley eastbourneWebIn this paper, Grashof's theorem is justified from the perspective of the occurrence of stationary configurations and uncertainty configurations of four-link chains.
