Numerical Simulation of Internal Flow Field of Barrel Grooved Gun Brake
In order to study the flow state of the internal fluid of the grooved recoil brake on the barrel wall of an artillery during the recoil motion of the artillery and the characteristics of the recoil force at different recoil speeds,the equivalent flow field model of the recoil brake was established using Fluent software.From the pressure and flow rate of the working chamber,the hydraulic pressure resistance coefficient K was derived,and the relationship between the flow rate,groove area and hydraulic resistance coefficient K was analyzed.The comparative analysis of simulation and experimental data shows that no matter the piston rod moves at a constant speed or a variable speed,the flow velocity of two different channels on the same section is almost equal,and the flow ratio of different channels on the same section is approximately equal to the area ratio of each channel.
