Noise Reduction of a High-speed Elevator

Numerical Simulations and Experiments on Flow Visualization

Abstract

To reduce the aerodynamic noise inside a high-speed elevator, flow visualization experiments and numerical simulations were performed and the flow behavior around its model was studied. These flow visualization results led to the understanding that in contrary to upward motion, during the downward motion the flow near the elevator door got accelerated. Based on these results, we mapped the flow pattern around the elevator model.
