Gas‐Dynamic Method of Determining Combustion Efficiency in a Model with Combustion

A method of determining combustion efficiency and test‐gas parameters along the combustion chamber with a supersonic velocity of air at the entrance is considered. The composition and properties of the test gas are determined by a thermodynamic calculation with allowance for dissociation and temperature dependence of the energy of internal degrees of freedom. The sources of errors and the influence of accuracy of initial data definition in a zero‐dimensional approach to determining the combustion curve and flow parameters are studied.
