Heat Transfer Effects on Pulsaltile Flow in Tubes with Slowly Varying Cross-sections
Keywords:
heat transfer, pulsatile, slowly varying tubes, stenosisAbstract
Analytic study of heat transfer effects on the pulsatile blood flow in tubes with slowly varying cross-sections is presented. The governing non-linear differential equations are solved using the perturbation methods of the type developed by Rao and Devanathan (1973). Expressions for temperature and Nusselt number are obtained and presented graphically for stenosis tubes. It is observed that the amplitude of the pulse, height of constriction and Reynolds number of the flow increase the temperature and heat transfer rates. Furthermore, it is seen that heat generated in stenosis arterial system could lead to body internal heat problem.
