Laminar free-convective heat transfer from a vertical isothermal plate to glycerol with variable physical properties

The steady laminar boundary layer flow of glycerol along a vertical stationary isothermal plate is studied in this paper. The density, thermal conductivity and heat capacity of this liquid are linear functions of temperature but dynamic viscosity is a strong almost exponential function of temperature. The results are obtained with the numerical solution of the boundary layer equations. Both upward and downward flow is considered. The variation of μ with temperature has a significant influence on the wall heat transfer and a much stronger influence on wall shear stress.
