Abstract
Расположение взрыво- и пожароопасных участков водородно-воздушной смеси по высоте конвективной колонки, образующейся над источником натекания водорода в помещение
Highlights
During leakage of hydrogen in the room convection column is formed over the source of leakage under the influence of buoyancy forces and the pressure drop between ones in the vessel with hydrogen and in the room
The dependence between the half-angle of convective column and the Froude number is obtained from comparison the results received by using the proposed model with the experimental data presented in the literature
There are presented the results of numerical experiments to determine the dependence between the heights of start and end points of the column falling on flammable and explosive hydrogen-air mixtures, and Reynolds number
