Abstract: | A theoretical study of the effect of variable fluid properties on the Blasius and Sakiadis flow with uniform suction at the
asymptotic state is presented in this paper. The investigation concerns air and water taking into account the variation of
their physical properties with temperature. Velocity and temperature profiles are presented as well as values of the displacement
thickness, momentum thickness, shape factor, wall shear stress and Nusselt number for different temperatures of the plate
and the ambient fluid. It is found that the nondimensional displacement thickness, momentum thickness, shape factor, absolute
wall shear stress and Nusselt number are identical in both Blasius and Sakiadib flow at the asymptotic state for a fluid with
constant properties. The same is valid for any fluid with variable properties if the temperature boundary conditions are the
same in Blasius and Sakiadis flow. |
