Title: Dynamics of heat exchange for gases in an underground cavity

Abstract

Heat exchange among the gaseous products in an underground explosion cavity has been studied by several authors. In this paper, the authors examine heat exchange processes for the gases in an explosion cavity for water-free and steam-saturated silicate soils. Calculations show that for cooling of the gases in an underground explosion cavity in the case of gas and water-containing soils, taking into account heat exchange between the molten material and the gas in the cavity during the mixing process, leads to an increase in the rate of cooling of the gases during the initial stage. Later, the rate of cooling slows down, the condensation time of silicon dioxide increases, and the duration of the implosion process increases by 6-7 times. The pressure in the cavity depends strongly on the water content of the soil. Thus, increasing the water content to 10% and including the implosion leads to an increase in the pressure inside the cavity, despite a drop in temperature. Up to 10% CO/sub 2/ in the soil has less effect on the pressure. In the case of soils with low gas and water contents, it is necessary to include heat exchange by leakage from the cavity.
