Th. Hsu et al., THERMAL CONVECTION OF MICROPOLAR FLUIDS IN A LID-DRIVEN CAVITY, International communications in heat and mass transfer, 22(2), 1995, pp. 189-200
Laminar mixed convection flow of micropolar fluids in a square cavity
has been investigated numerically. The flow in the cavity is induced b
y the combined shear force and buoyancy force resulting from the motio
n and heating of the upper lid. Parametric studies of the effects of m
icrostructure on the fluid flow and heat transfer in the cavity have b
een carried out. The flow phenomena are discussed for a range of Grash
of number and Reynolds number. Numerical computations are also perform
ed for Newtonian fluid for comparison. The numerical results indicated
the strong influence of material parameter, such as vortex viscosity
and spin gradient viscosity, on the flow structure and heat transfer.
