| Abstract: | The flow field and temperature profile of an afterburning cone at various kinds of cooling were calculated by the numerical simulation method.The infrared radiation characteristics of the afterburning cone were analyzed using the calculation software.The result shows that the effectiveness of cooling with the holes and slots combination is better than that with the hole or with slots.The infrared radiation intensity of afterburning cone decreases to 68.49% at the colling with the holes and slots. |
