Simultaneous transient conduction and radiation heat transfer with heat generation is investigated. Analysis is carried out for both steady and unsteady situations. two-dimensional gray cylindrical enclosure with an absorbing, emitting, and isotropically scattering medium is considered. Enclosure boundaries are assumed at specified temperatures. The heat generation rate is considered uniform an...

We present a new Control Volume Finite Element Method (CVFEM) for the drift-diffusion equations. The method combines a conservative formulation of the current continuity equations with a novel definition of an exponentially fitted elemental current density. An edge element representation of the nodal CVFEM current density in the diffusive limit motivates this definition. We prove that in the ab...

Three dimensional heat and mass transfer in a metal-hydrogen reactor are numerically studied using the control-volume-based finite element method (CVFEM).The distributions of the temperature and the hydride density on the hydriding process is presented and discussed. The effects of dimensions reactor, imposed hydrogen pressure, inlet temperature and hydride thermal conductivity in the reaction ...
