Abstract

Abstract

In order to investigate the characteristics of muzzle noise, a numerical study on jet noise induced by complex flows discharging from 7.62 mm gun is achieved. Because of the complex flows structure, it is not easy to study muzzle noise by direct simulation of CAA in current level of computational condition. CFD-CAA hybrid method is applied. At first, the muzzle flow is calculated by using LES. Using the obtained data, the jet noise is carried out by using FW-H equation. The feasibility of the numerical method is verified by comparing with the experiment. Then, the jet noise of 7.62 mm gun is numerically studied by using the hybrid method. Based on the numerical results, the jet noise directivity is analyzed and the contour of sound pressure level is also drawn. Results indicate that jet noise is mainly concentrated in the near muzzle region and the maximum jet noise mainly occurs in the range of 30°-60°.
