Research on aerodynamic characteristics and energy consumption of elevator deflectors under different speed conditions

Abstract In order to improve the aerodynamic performance of high-speed elevators, it is necessary to design a reasonable deflector for the elevator car. In this paper, five types of typical deflectors are designed, and the elevator system model including the car, the counterweight and the hoistway is established. Using Fluent computational fluid software, the dynamic grid analysis method is used to carry out transient numerical simulation of the aerodynamic characteristics of the elevator. The variation law of performance parameters such as aerodynamic drag, energy consumption. The research shows that the influence of different deflectors on the aerodynamic performance of the elevator varies greatly under different speed conditions, and different types of deflectors have their own optimal applications. The research work provides a useful reference for the design and selection of the elevator deflector.
