Research on the drags of high speed elevator with different height diversion cover

Abstract

Abstract. The three-dimensional flow of high speed elevator is numerical simulated using the Computational Fluid Dynamics Method (CFD). The car of high speed elevator has dimensions of length 2.3m, width 1.7 m and height 2.4 m. The shape of diversion cover is conic. The flows of high speed elevator with different height diversion cover are simulated, and then the drags are analyzed. It is present that the drags of the car are decreased when the height of diversion cover increases.
