The invention provides a high-speed elevator fairing selection method, relates to the technical field of elevators, and not only solves the problems that an RANS method only aims at a single problem and is small in calculation amount, but also avoids the problem that an LES method needs huge computer storage capacity and calculation capacity by combining an RANS numerical simulation method and an LES numerical simulation method. On the basis of an embedded RANS/LES mixing method, a synthetic vortex method is adopted to generate turbulence information of an interface, air pressure change of a lift car during operation in a shaft is calculated, then a fairing model with a plurality of characteristics is constructed according to actual requirements, the model is imported into Fluent software to conduct three-dimensional modeling simulation, simulation results of fairing of different structures are obtained, and the fairing model is used for simulating the fairing of different structures. And comparing various models and optimizing the appearance, and finally obtaining an optimal fairing as a selection reference.
