CALCULATION OF THE STATE OF PRODUCTS OF EXPLOSION BY THE METHOD OF MEASUREMENT OF PARAMETERS OF SHOCK.
Abstract
A method is presented for the investigation of the state of combustion products in a closed pipe, by which the relationship between parameters of combustion products of the mixture CH4 + 4O2 and the coefficient of heat transfer on the one hand and time on the other can be calculated. The law is established of the heat transfer between a gas and the wall of a pipe during nonstationary flow of gas, characteristic for conditions of the experiment, which does not differ greatly from the law described for stationary flow. It is shown that in the conditions of the experiment, where there is a sharp change in the parameters of a gas, the system reaches a state of thermodynamic equilibrium in time of the order of 0.001 seconds. Equilibrium begins to be lost in a time of the order of 0.0001 seconds. (Author)
