Fossil fuels that can't be replenished are limited resources that will eventually run out in the next few years. Humans only capture just a tiny amount of the massive quantities of renewable wind energy that nature be endless. A numerical analysis on wind energy harvesting from a moving subway train is suggested in light of this. Trains and subways produce amazing wind gusts that can be converted into useful electrical energy on a regular basis. In order to accomplish this, a Savonius wind turbine is positioned in a subway tunnel to capture the wind energy generated by a running train. Slipstreams traveling at extremely high speeds are created by trains moving through the tunnel. The Savonius wind turbine will self-start and produce energy by absorbing the boundary layer regime created by the slipstream phenomena. The self-starting turbine captures air from all directions and generates usable power without the need for a yaw mechanism. Ansys Fluent is used in the current work to run a two-dimensional numerical simulation with modified turbine blade designs to calculate the amount of torque of the rotor that produced by the wind gust caused by the moving train in the tunnel
