SPECIAL FEATURES OF PROPAGATION OF HYDROGEN IN A BUILDING
S. V. Puzach UDC 614.841.4 A three-dimensional mathematical model for calculating heat and mass transfer in propagation of hydrogen in a building that allows for gas exchange with the environment through an opening has been proposed. Based on numerical calculations performed by the proposed model, the author revealed certain features of the concentration fields of hydrogen in the case of its inflow at the floor level. It is shown that the dimensions and location of the explosion- and fire-hazardous zones change considerably during the process. JEPTER7492020007 JEPTER749207
