Numerical simulation has been carried out for heat transfer of laminar channel flow with an immiscible, high-viscosity droplet, in order to elucidate the heat transfer in micro vessels in case of skin burns or chilblains. The droplet expresses an erythrocyte or a group of erythrocytes. The tank treading phenomena of the erythrocyte can be expressed by solving the NS equations inside the droplet. The plasma is assumed to be Newtonian fluid. The governing equations are solved with a non-uniform grid system and finite difference schemes. The modified Volume-Of-Fluid (VOF) method is used for estimating the deformation of the droplet. The initial shape of the droplet is either sphere or ellipsoid. It is found from the computational result that low-temperature fluid is pushed into the near-wall region by the wake flow of the droplet.
