The influence of nonabsorbable admixtures on heat and mass transferprocesses in metal hydride systems at hydrogen absorption

摘要

The paper presents numerical results on hydrogen absorption in metal hydride reactor.Mathamatical model of heat and mass transfer in metal hydride bed for hydrogen absorptionfrom a gas mixture is proposed. A theoretical model for effective thermal conductivity takinginto account the precense of nonabsorbable admixtures is described. A sensitivity study ofheat and mass transfer in metal hydride reactor to absorption kinetics, interface heat exchangeand natural convection is carried out.
