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.).

A critical value exists for the Rayleigh number, above which fluid motion occurs.

WebDec 6, 2024 · The graphical findings show how temperature, pressure rise, concentration, pressure gradient, nanoparticle fraction, and stream functions affect key physical parameters of interest. It is revealed that the velocity value rises as the velocity slip parameter, temperature, and solutal Grashof number rise. WebResults show that salt-finger instability is excited over a wide range of thermal and solutal Grashof numbers.
