RT Journal Article ID 60306a157b2665b6 A1 Juncu, Gheorghe T1 NUMERICAL STUDY OF THE MOMENTUM AND CONJUGATE HEAT TRANSFER BETWEEN A SPHERE AND A MICROPOLAR FLUID FLOW JF Heat Transfer Research JO HTR YR 2019 FD 2018-10-02 VO 50 IS 1 SP 65 OP 87 K1 micropolar fluid K1 sphere K1 axisymmetric flow K1 forced convection K1 conjugate heat transfer AB The flow of a micropolar fluid past a rigid sphere and the conjugate heat transfer from the sphere to the micropolar fluid are investigated numerically for moderate Reynolds numbers. The results indicate that the flow field is governed by the parameter that characterizes the interaction between the fluid and the sphere's surface, α. For α = 1 the flow is similar to that of a Newtonian fluid. The influence of the non-Newtonian effects increases when 0 ≤ α < 1. The effects of non-Newtonian fluid parameters on the heat transfer rate depend on the thermal wake phenomenon.
