SIMULATION RESEARCH ON FLOW FIELD DISTRIBUTION IN ARTILLERY TURRET UNDER THE SIMULTANEOUS ACTION OF EXHAUST FAN AND BLOWER

Abstract

Aimed at the problem of after multiple firings of vehicle-mounted artillery, the gas in the turret remains, and the concentration is high, which endangers the safety of personnel in the tower. When the blower and the exhaust fan are working at the same time, a numerical simulation study based on computational fluid dynamics is carried out, and the flow field distribution results under different fan power working conditions are obtained. The simulation results have important reference significance for understanding the changing law of the medium in the turret under the action of the fan and the selection of the fan.
