Lattice Boltzmann method is used to simulate natural convection in blood flow through stenotic artery. The problem of natural convection in stenotic artery is considered and the influence of elevated temperature and material properties is studied on the flow properties. A porous like square stenotic medium in a human artery with fluid (blood) at the left wall of the geometry and the north wall kept to a normalized temperature of 1.0 is considered. The flow properties like velocity profiles, streamlines, temperature profiles and the rate of heat transfer are then studied with respect to the material properties like porosity and permeability and flow parameters like Rayleigh number and power law index.
