Mathematical simulation of heat and mass transfer in a hydride accumulatorof hydrogen

A mathematical model is suggested of simultaneous calculation of the proces ses of heat and mass transfer in a gas medium in a room with openings durin g the escape of hydrogen from a hydride accumulator under conditions of fir e. A numerical investigation is performed of the dependence of the mass flo w rate of hydrogen into the room through the point of loss of seal in the h ydrogen how train, the parameters of the gas medium in the room, and natura l gas exchange with the ambient medium on the thermal properties of the mat erial of enclosing structures for a model fire and a model hydride accumula tor. It is demonstrated that the entire mass of hydrogen stored in the accu mulator is desorbed during the time of fire.
