Abstract

Viscoelastic flow structure and heat transfer around a sphere is being studied. Fluid motion is described by equations of conservation of mass, momentum and thermal energy with rheological constitutive equation of Phan-Thien Tanner (PTT). This model is a generalized Maxwell type model with two additional parameters, developed from kinetic theory of polymers. Numerically shown the considerable influence of fluid stress relaxation time and temperature difference between sphere and medium on viscoelastic structure of the flow in wake. Investigation results of the heat transfer exchange in non-isothermal flow around sphere with slip and noslip condition on walls are given.

Keywords:

viscoelastic fluid, axisymmetric flow, heat transfer
