Abstract
The design of high-speed railway lines (HSR) requires mandatory consideration of loads from the aerodynamic interaction of a moving train, the air environment and infrastructure facilities, acting both on structures and facilities, and on the train itself. Software systems of computational fluid dynamics are most expedient to determine the nature and intensity of the load.
To find the optimal approach to modelling the processes of aerodynamic interaction between a moving high-speed train and the air environment, as well as to assess the degree of validity of the simulation, a series of calculations were performed in the ANSYS CFX software environment using various approaches to the construction of calculation models (the sliding grid method and the immersed solid method). An analysis of the results of the performed calculations makes it possible to determine the area of rational application of the considered approaches in the development of computational models of aerodynamic interaction.
To verify the developed calculation models, experimental measurements of the aerodynamic impact of Sapsan high-speed electric train on the air environment were performed. Also, the developed models were verified based on the results of similar international experimental studies. Comparison of the results of numerical simulation and experimental measurements allows us to conclude that the developed computational models are sufficiently valid and can be further applied.
