The use of numerical simulation in the analysis of aerodynamic problems in transport

Abstract

The study of the aerodynamic impact of rolling stock on the railway infrastructure is carried out either with experimental methods or with numerical simulation methods. The use of numerical simulation methods allows you to safely and quickly obtain the necessary data. An important task is to determine the factors that affect the aerodynamics of the rolling stock. To study aerodynamic processes in transport it is proposed to use the Frozen Rotor method in combination with the Large Eddy Simulation, which can be implemented using the Solid Works Flow Simulation software package. This method makes it possible to obtain a high-quality picture of the distribution of air flows in the boundary and main layers.
