摘要：Active cooling technology is widely used in navalgun. The composite cooling system with external circulatingwater cooling technology and internal spray cooling technologyis adopted for 100mm medium caliber naval gun. In order tooptimize the cooling efficiency of barrel and improve thecombat effectiveness and safety performance of naval gun, it isof great significance to study the internal fluid field and barreltemperature field under the condition of composite cooling.Regarding 100mm naval gun as the object of the research, thispaper proposed to use numerical analysis method combiningclassical interior ballistics with computational fluid dynamics toestablish the transient CFD three-dimensional model based onmultiphase flow. Physical quantities such as temperature,velocity, species distribution, and interphase mass transfer inthe calculation domain were calculated through simulation, andthe temperature changes of the barrel with and without thecooling system were compared and analyzed. Finally, the lawsof the gun barrel were obtained, which provided references forfurther study.
