Enhancing Piston Effect in Tunnels by BK180 is a document available to read on EtoBox.

This document discusses using an aerofoil attached to the sides of a train to enhance the piston effect in underground railway tunnels. A computational fluid dynamics model was developed and validated to investigate how positioning an aerofoil at different angles could influence the volume of air displaced by a moving train. The results showed that using a fixed 10° angle could increase air displacement by 3% without increasing aerodynamic drag on the train. Using varying angles during different phases of m
