A Porous Model of Tumor in Hyperthermia Therapy with Convection of Blood Flow
نویسنده
چکیده
This study investigates the temperature and thermal dose of a tumor in hyperthermia therapy with non-local equilibrium. The thermal model assumes the tissue with blood vessel distribution as a porous media and uses the convection terms instead of perfusion terms in energy conservation equations for both tissue and blood. By using numerical method, this study calculates the temperature and thermal dose response of tissue for different vessel diameters and blood velocities with keeping constant porosity. Through the accuracy and model comparison, the results show that the temperature responses of tissue for different cases by this numerical method are reliable, and the model is suitable for various vessel diameters and porosity.

In present work forced convection flow in a channel partly filled with a porous media under asymmetric heat flux boundary condition has been investigated. The porous material is distributed on the one wall. Darcy–Brinkman and LTNE model have been assumed in order to solve momentum and energy equations, respectively. Fully developed conditions are considered in order to solve velocity and the te...
