Thrust of a contracting nozzle

  • 28 Accesses


A study is made of the influence of the nonuniformity of the parameters due to the two-dimensional nature of the flow on the specific thrust of a contracting nozzle. It is shown that for continuous flow of an ideal (inviscid and nonheat-conducting) gas the specific thrust in the supercritical regimes exceeds the value determined using the one-dimensional theory for the same stagnation parameters of the gas; in the subcritical regimes the specific thrust of the contracting nozzle is equal to the value found from the one—dimensional approximation.
