NUMERICAL SIMULATION OF AERODYNAMIC PROCESSES OF AIR MASS MOVEMENT IN UNDERGROUND TUNNELS TAKING INTO ACCOUNT PISTON IMPACT OF ROLLING STOCK
Abstract and keywords
Abstract (English):
Purpose: To consider the issue on verification of numerical model of air exchange during the movement of a train in a subway tunnel, taking into account the process of interaction of regular ventilation with the piston effect of the displaced air by the body of the moving train. Methods: Data scanning and processing. The equipment used was a pressure cylindrical Pitot tube PFM 2 for measuring differential pressure and air flow velocity, volumetric flow and temperature. Results: The dynamic structure of disturbed fluid media at the time of rolling stock arrival and departure has been established. Practical importance: Factors of design solutions of tunnel portal part affecting the process of air exchange at the combined work of ventilation and piston effect of moving trains have been determined.

Keywords:
piston effect, Pitot cylindrical pressure tube PFM, SCB cabinets, CFD modeling, pressure field, anemometer, air temperature
