| Abstract: | The numerical models of an aeroengine exhaust nozzle and its jet flow field were built based on the Navier-Stokes equations. The infrared radiation characteristics of the exhaust nozzle at non-afterburning condition were obtained by infrared radiation characteristics calculation program compiled by the integrated method of the Radiation Transfer Equation （RTE）. The infrared radiation characteristics of the modeled exhaust nozzle were measured by the test. The results of numerical simulation and measurement for infrared radiation characteristics for the exhaust nozzle in the. spectrum range of 3.0-5.0 μm were given. The results show that the numerical simulation are in accord with the measurement. |
