ABSTRACT |
This paper deals with the study of heat transfer in unsteady axsymmetric rotational flow of Oldroyd liquid. Constitutive equations of the problem have been developed and solved by applying Laplace transform technique. Expressions for fluid velocity, temperature, skin-friction and rate of heat transfer are obtained. After computerization with the numerical values of fluid parameters, the velocity and temperature profiles are plotted. Numerical values of skin-friction and rate of heat transfer are entered in tables. It is observed that elasticity of the fluid reduces the phase of oscillation and the increase in Prandtl number decreases the temperature of fluid.
