Numerical simulation of heat transfer in blood vessels

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 hea...

In this study, the blood flow and heat transfer in an artery under various heating conditions have been numerically simulated.
