Abstract

A rapid nozzle performance analysis methodology and project for two-dimensional convergent-divergent nozzle have been developed. A one-dimensional isentropic flow model is employed to calculate the parameters of nozzle internal flow field. And the skin friction coefficient is used to correct the non-isentropic flow effect. Method of integral around the nozzle surface is used to compute the thrust. The divergence factor is applied to correct the nozzle thrust loss which because that the nozzle exit flow is radially divergent. Calculating the nozzle thrust coefficient in three different working conditions, including over/perfect/under expansion conditions, by using nozzle performance analysis project and numerical simulation respectively. The results of the project, numerical simulation and experiment data have a good agreement in different working conditions, and the error of thrust coefficient is less than 2%. The calculation accuracy is contented to the requirements of calculations.
