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-hydrogen reactor during desorption is presented in this paper. A mathematical model has been established and solved numerically by the method of finite domains. The numerical simulation is used to present the time-space evolution of the temperature, the pressure and the hydride density in the reactor and to determine the sensitivity to some parameters (reactor geometry, outlet pressure, temperature of heating fluid and heat conductivity). This simulation allows us to study the effect of neglecting the term related to heat transport by convection in the model.
