INFLUENCE OF HEAT GENERATION ON DETONATION IN REAL GAS |
| description |
The study of detonation processes in gaseous media is of interest for the coal mining, aviation, aerospace industries, and hydrogen energy. Under high pressure conditions during the passage of a detonation wave, it is necessary to take into account the equation of state of a real gas, the effects of endothermicity and exothermicity.
The paper considers the flow of real gas through a plane detonation wave. A modified Rankine-Hugoniot equation has been obtained to describe the dynamics of changes in the parameters of a van der Waals gas flow when it passes through a detonation wave.
An equation for the maximum increase in gas density during the passage of a detonation wave is obtained. The influence of parameters A and B in the van der Waals gas equation of state on the asymptote of the maximum increase in density is shown. It follows from the equation that the asymptote of the maximum increase in density shifts to the region of lower values of r2/r1 with an increase in the value of parameter B, and parameter A does not affect the position of the asymptote of the maximum increase in density.
The influence of heat release and thermodynamic properties of gas on the pressure jump in the detonation wave is shown. Pressure jumps in a van der Waals gas are greater than in the case of an ideal gas. Calculations have shown that an increase in parameter A slows down the increase in pressure in the detonation wave, and an increase in parameter B enhances it. An increase in heat release leads to an increase in the pressure jump, to an equidistant increase in the Hugoniot curve compared to the case without heat release. |
