title: Improvement of the Pennes Equation in the analysis of heat transfer phenomenon in blood perfused tissues.
abstract: Heat in body is generally transferred by blood perfusion system but its mechanism varies in whole body systems. The Pennes Equation is a heat transfer equation that is generally used as a balance equation in bioheat transfer analysis. Although this equation is usually used in applied problems, it is not accurate in details. Factors that are not incorporated in this equation are blood perfusion and its effect on heat transfer rate in tissues. In this paper an equation is proposed to calculate the rate of heat transfer by blood flow in capillaries, using mathematical methods. By adding this term to the Pennes equation, it can be optimized.
