STUDY OF 2-DIMENSIONAL HEAT AND MASS-TRANSFER DURING DESORPTION IN A METAL-HYDROGEN REACTOR

A study of two-dimensional dynamic heat and mass transfer in a metal-h ydrogen reactor during desorption is presented in this paper. A mathem atical model has been established and solved numerically by the method of finite domains. The numerical simulation is used to present the ti me-space evolution of the temperature, the pressure and the hydride de nsity in the reactor and to determine the sensitivity to some paramete rs (reactor geometry, outlet pressure, temperature of heating fluid an d heat conductivity). This simulation allows us to study the effect of neglecting the term related to heat transport by convection in the mo del.
