Experimental-based study of the aerodynamics of super-high-speed elevators

Elevators can be considered to be the most important building services system in a modern super-high-rise building. At the same time, the speed record has also been elevating with recent record of 1010 m/min. The design and construction of super-high-speed elevators are thus demanded. The primary experimental measurements for the aerodynamic characteristics of super-high-speed elevators were conducted using a physical model for simulation. The instantaneous speed of a falling elevator car at five different positions as well as the average pressure in front of and behind the car along the hoistway were measured while four scenaria with different shapes of car design were tested. Parameters associated with the hoistway, including the open ratio and the blockage ratio, varied in the experiments. Results were produced with respect to the car having different shapes and hoistway parameters. The nondimensional pressure differences for different shapes of car and hoistway parameters were analyzed so that several...
