At higher Grashof numbers, the boundary layer is turbulent; at lower Grashof numbers, the boundary layer is laminar, that is, in the range 10 3 < Gr L < 10 6. Mass transfer. There is an analogous form of the Grashof number used in cases of natural convection mass transfer problems. 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 fluid. … 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.).
