The numerical study is performed for study of the viscoelastic flow characteristics and heat transfer around sphere. The flow of liquid is described by equations of conservation of mass, momentum and thermal energy with rheological constitutive equation of Phan-Thien Tanner(PTT). Thismodelrepresents generalizedMaxwell typemodel with two additional parameters developed from kinetic theory of polymers. The nonlinear behaviour of fluid velocity behind body (<<negative wake>>) is observed.
