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.
