| Abstract: | In order to study the influence of different structures of muzzle brakes on the muzzle flow field of amphibious artillery, CFD technology was used to process the projectile combined with moving grid technology, and the three dimensional unsteady compressible flow Euler equation and Realizable k ε turbulence equation were used to numerically simulate the muzzle flow field. The results show that the lateral pressure at the edge position of the front face of the hatch under the impact muzzle brake and the lateral pressure on the lower edge of the front face of the hatch are higher than the pressure of the reverse impact type. In the transverse position of the upper surface of the car body under the muzzle, t=1.0 ms, the overpressure value under the impact muzzle brake is about 0.8 MPa higher than that of the reverse shock type. The research results provide a data basis for the design of the muzzle chassis of the amphibious artillery and the selection of the brake structure. |
