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 therm...

We study the thermal equilibrium of nonlinear Klein-Gordon chains at the limit of small coupling (an-ticontinuum limit). We show that the persistence distribution associated to the local energy density is a useful tool to study the statistical distribution of so-called thermal breathers, mainly when the equilibrium is characterized by long-lived static excitations; in that case, the distributio...

Modelling of heat transfer in non-equilibrium reacting gas flows is very important and promising for many up-to-date practical applications. Thus, calculation of heat fluxes is needed to solve the problem of heat protection for the surfaces of space vehicles entering into planet atmospheres. In high-temperature and hypersonic flows of gas mixtures, the energy exchange between translational and ...

Forced convective heat transfer in a packed bed in the presence of collimated irradiation and under local thermal non-equilibrium is analyzed in this work. Both the collimated and diffusive radiative transfer processes are accounted for using the modified P-1 approximation. Two boundary condition models considering different limiting conditions at the wall which couple radiation and convection ...

The present work involves numerical simulation of a steady, incompressible forcedconvection fluid flow through a matrix of porous media between two parallel plates at constanttemperature. A Darcy model for the momentum equation was employed. The mathematical model forenergy transport was based on single phase equation model which assumes local thermal equilibriumbetween fluid and solid phases. ...

The glass transition, extensively studied in dense fluids, polymers or colloids, corresponds to a marked evolution of equilibrium transport coefficients on a modest change of control parameter, such as temperature or pressure. A similar phenomenology is found in many systems evolving far from equilibrium, such as driven granular media, active and living matter. Although many theories compete to...
