Abstract In order to analyze the performance of the external cooling method
for the rapid firing gun barrel, an accurate numerical simulation
modeling is important. A mathematical model of heat transfer for
external cooling gun barrel was established by using finite
difference method. The temperature history of gun barrel with
natural cooling and external cooling method were calculated. The
influence of the coolant vaporization on cooling effect was
considered in the calculation. The results show that the temperature
gradient in the barrel wall is very large. Through the contrast
analysis of calculation results it can be seen that the cooling
effect of the external cooling method is more and more remarkable as
the shooting number is increasing. Especially, the gun tube
temperature drop is the most obvious in the firing interval. A
series of experiments were performed for the gun barrel. The
calculation results were discovered to agree with the experimental
data. From the results can be concluded that the external cooling
method is an effective means of thermal control for rapid firing gun
barrel. Under reasonable firing controlled schedule, the gun barrel
life can be effectively improved by using external cooling method.
