Gas explosion and detonated waves parameters were determined for an ideal gas in an enclosed volume with rigid walls in gas systems on the border between explosive gases and liquids for different boundary conditions. Examples of the explosion of the combustible mixture of methane and air, with full and partial oxidation of methane have been considered.
The method of increasing the efficiency of hydromechanized extraction of ferromanganese nodules of the Baltic Sea is proposed. The object of the research are the processes occurring in the perforated insert located behind the power unit in the bottom zone and designed to remove excess water and sludge. The design of the perforated spigot and the relationship between its length and the parameters of the extraction process are described. The design scheme of the laboratory bench, the data obtained during the experiment and the results of their primary processing are presented.
