层间冷却是火炮身管冷却的一种有效方式
分析连发时这种冷却身管的冷却特点.以某速射火炮身管为研究对象
采用ANSYS的FLOTRAN模块
应用流固耦合的方法进行温度分析.通过与空气冷却对比
层间冷却能大幅度减少冷却时间
从而减少射击规范中冷却间隔时间;冷却过程中身管截面内出现了同一半径不同温度的分布现象;冷却液流速超过一定值后
提高流速对身管的冷却差别不大.这种数值仿真方法把流固边界条件处理为内边界条件
能够较好地模拟身管冷却的过程
为层间冷却身管的设计提供了一种数值计算方法.
Interlayer cooling is an effective way of barrel cooling
and the analysis on cooling characteristics is conducted under continuous firing.Taking a certain kind of rapid-fire gun as the research object
the FLOTRAN module of ANSYS software was used to analyze the heat transfer of the interlayer cooling based on fluid-solid coupling method.Compared with air cooling
interlayer cooling can reduce the cooling time greatly so that the time interval of cooling in shooting criterions can be reduced.The phenomenon of the same radius with different temperature exists in cross-section in the process of cooling.The increase of velocity of cooling liquid did not improve cooling obviously when the velocity exceeds a certain value.This numerical simulation method deals with the fluid-solid boundary conditions as internal boundary conditions
can simulate the process of cooling barrel better and provide a numerical calculation method for the barrel cooling design.
