Grashof's theorem
WebBuckingham π theorem (also known as Pi theorem) is used to determine the number of dimensional groups required to describe a phenomena. According to this theorem “the number of dimensionless groups to define a problem equals the total number of variables, n, (like density, viscosity, etc.) minus the fundamental dimensions, p, (like length ... WebThese variants can be derived from the theorem of Grashof. Grashof’s condition for four-bar linkages states: The shortest link of a four-bar linkage can fully rotate in relation to its neighbouring links, if the sum of the lengths of the shortest and longest link is smaller – or at least equal, in the limit case – than the sum of the ...

WebIn fluid mechanics, the Rayleigh number ( Ra, after Lord Rayleigh [1]) for a fluid is a dimensionless number associated with buoyancy -driven flow, also known as free (or natural) convection. [2] [3] [4] It characterises the fluid's flow regime: [5] a value in a certain lower range denotes laminar flow; a value in a higher range, turbulent flow.

WebJul 5, 2024 · The dimensionless parameter represents the natural convection effects and is called the Grashof number. Grashof number, Gr, as the ratio between the buoyancy force and the viscous force: G r = g β ( T s − T ∞) L c 3 ν 2 Nusselt number is a function of the Grashof number and the Prandtl number alone. Nu = f (Gr, Pr) Download Solution PDF WebThe Grashof number ( 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 and is analogous to the Reynolds number. [1] It's believed to be named after Franz Grashof.
