Abstract: Based on the Navier-Stokes equation of compressible viscosity fluid and thek-εturbulence model, turbulent flow around a TR (Transrapid) maglev train with a speed of 430 km/h was investigated using the finite volume method, and the pressure and velocity distributions of slipstream around the train were gained. The research results show that the changes of velocity and pressure within 2 m away from train s top and two side surfaces are respectively more than 10 m/s and 1.3 kPa, while at the height of 2 m away from the ground, they are respectively less than 5 m/s and 0. 7 kPa.
