【Abstract】 In this paper, the theory of steady compressible fluid flow of 1-D is used to present the necessary boundary conditions for temperature field calculation in a tunnel when an internal combustion engine powered train is crossing. The calculated results show that the analysis and results in this paper are reasonable.更多还原
