Estimation of the detonation cell size in gases

A simple method to calculate the parameters of a shock wave in a space between the shock wave front and the Chapman-Jouguet plane is considered. Solving a velocity equation, one can calculate the pressure, density, and temperature of the gas, as well as determine the size of a detonation region in a one-dimensional approximation. The dependences of the detonation region size on input parameters are derived. From these dependences, one can estimate the run of the same curves in the real situation.
