NUMERICAL CALCULATION FOR OBTAINING ANALYTICAL EXPRESSION FOR THE DISTRIBUTION OF VELOCITY AND STRESS PLACED ON HIGH-SPEED TRAIN BY FRICTIONLESS COMPRESSIBLE FLUID (AIR) FLOW MOVING HORIZONTALLY AT A CONSTANT RATE

In this study a numerical calculation of velocity distribution in a frictionless jet flow around a running high-speed train is made. Also the analytical function for the calculation of velocity distribution and airflow stress on high-speed train is found. The obtained data will be used for the maintenance of high-speed train operation safety and environmental security, as well as for the erection of buildings, structures or dwelling houses in the vicinity of railways.
