Abstract

Abstract

The viscoelsatic boundary layer flow and heat transfer near a verticaliso therm al impermeable surface and in a quiescent fluid were examined. The governing equations were formulated and solved numerically using the MackCormak's technique. A comparison with previously published results on special cases of the problem shows excellent agreement. Represen tative results for the velocity and temperature profiles, boundary layer thicknesses, Nusselt numbers and localsk in friction coefficients are shown graphically for different values of viscoelsatic parameter. Ingeneral, it is found that the velocities in creaseinside the hydrodynamic boundary layers and the temperatures decrease in side the thermal boundary layers for the viscoe lsatic fluid as compared to the Newtonian fluid due to favorable tensile stresses. Consequently the coefficient of friction and heat transfer are enhanced for higher viscoe lsatic parameter.
