Piston effect refers to the forced-air flow inside a tunnel or shaft caused by moving vehicles. It is one of numerous phenomena that engineers and designers must consider when developing a range of structures. Visa mer In open air, when a vehicle travels along, air pushed aside can move in any direction except into the ground. Inside a tunnel, air is confined by the tunnel walls to move along the tunnel. Behind the moving vehicle, as air has … Visa mer The piston effect has to be considered by building designers in relation to smoke movement within an elevator shaft. A moving elevator car forces the air in front of it out of the shaft and pulls air into the shaft behind it with the effect most apparent in elevator … Visa mer Passengers and crew may experience ear discomfort as a train enters a tunnel because of rapid pressure changes.
