| Abstract: | In this paper, the unsteady differential equation group of turbulent flow boundary layer in gun tube was established, and based on the model of quasi two phase core flow and turbulent boundary layer flow the heat transfer in gun tube was computed. Compared with experimental results it was proved that the model can simulate the distribution of temperature on gun tube. This paper will have a great significance on the gun tube life. |
