STUDY OF HEAT AND MASS-TRANSFER IN A METAL HYDROGEN REACTOR

A study of two-dimensional and dynamic heat and mass transfers during absorption of hydrogen in a metal-hydrogen reactor is presented in this paper. A mathematical model has been established. The resolution of the resulting system of equations has been realized numerically by the method of finite elements. The numerical simulation permitted to represent the time-space evolution of the temperature, the pressure and the hydride density in the reactor and also to determine the dependence on reactor geometry, the inlet pressure and the inlet temperature.
