There is inadequate work done on tapered and stenois blood vessel under thermotheraphy, experimental studies being impossible to be conducted since the system is unlike mechanical system which could be modeled in the lab. In this study, the blood flow and heat transfer in an artery under various heating conditions have been numerically simulated. Three different cases of blood vessels are considered: straight vessel, converging tapered vessel and stenois vessel. Constant heat flux was applied at several intensities in each case. It was shown that the flow simulated at the vena contracta is...

The purpose of this study is to investigate the effects of an external heat flux applied to a bifurcated artery which surrounded by the human tissue during thermal therapy. Two different 2D models have simulated, first the bifurcated artery, and second the stenosed bifurcated artery with two symmetrical stenosis. This study helps a lot to determinate the principal data for achieving the goal of experimental simulation. Three different external heat fluxes, three different durations and different physical properties have been investigated. Non-dimensional blood and tissue temperatures were...
