VERIFICATION OF MODEL FOR CALCULATION OF LOSSES DUE TO SUBMERGED NOZZLE

Modern methods of numerical simulation are used to verify the model for investigating the perfection of flow in engines with submerged nozzles. Based on a comparison of the specific impulse losses associated with the submerged nozzle, satisfactory verification results were obtained. The possibility of investigating the consumption factor of a submerged nozzle as a function of the geometric characteristics on its gas-dynamic component is shown
