초고속 자기부상 열차의 공력학적 특성

In this paper, the Navier-Stokes equation with the equation of the k- e model of turbulence model were solved numerically for 3 dimensional flows around 550 km/h high speed magnetically levitated (Maglev) train. Maglev train travels on a high railroad at high speed unlike normal train. To simplify the situation, we assumed that the train ran in the air. At the velocity 550 km/m, the drag coefficient was 0.35 and pressure drag was 91 % of the drag. The drag was increased with the proportion for the square of velocity.
