Numerical Simulation of Three Dimensional Interior Flow Field in Gun Recoil Mechanism Based on Dynamic Meshing Technique
The accurate development rules of interior flow in recoil mechanism of gun are difficult to obtain by experiment, because of the recoiling course of gun is transient and the inner structure of recoil mechanism is complex as well as the interior flow in it. However, numerical simulation can be regarded as an effective way to acquire the rules. The 3D NavierStokes equations and RNG k—Z turbulence model were used to set up the interior turbulence flow field. Layer dynamic meshing technique was adopted to describe and control the motion of recoil piston. The numerical distribution of interior flow field in recoil mechanism was acquired according to the CFD numerical simulation results. The development rules of interior flow field when recoiling course begin and the moment of highest presssure in working chamber appeared were studied and analysed. This methods can provide guidance for study of interior flow field.
