可再生的化石燃料是有限的资源，最终会在不久的将来耗尽可再生的风能，但人类会考虑到这一点每天都可以将其转移到有用的电能的风中。 Savonius风力涡轮机在隧道中裁剪产生的风能。 Savonius风力涡轮机在本研究中产生动力，使用开源工具进行了二维数值模拟OpenFoAm®与Pimpledymfoam求解器与六个自由度的网状运动求解器sixdofrigidBotommotion和K – turmution建模，以测量转子从隧道中的超速升级列车产生的风转旋翼预测的扭矩量。启动涡轮机，没有任何偏航机构，需要涡轮机从任何方向收集空气，并将其转换为有用的功率。
Nonrenewable fossil fuels are finite resources that will ultimately deplete in near future. Nature sheds colossal amount of renewable wind energy but humans harvest a morsel. Taking this into account a numerical study is proposed on wind energy harvesting from a speeding subway train. Subways trains generate a remarkable gust of wind that can be transferred to useful electrical energy on daily basis. To this aim, a numerical analysis is modeled by placing Savonius wind turbine in a subway tunnel to crop the wind energy produced from the speeding train. The passage of train in the tunnel generates very high velocity slipstreams along the length of the tunnel. The slipstream phenomena develop a boundary layer regime that will be absorbed by the Savonius wind turbine to self-start and generate power. In the present study, a two-dimensional numerical simulation with modified turbine blade design is carried out using open source tool OpenFOAM® with PimpleDyMFoam solver coupled with six degrees of freedom mesh motion solver sixDoFRigidBodyMotion and k–ɛ turbulence modeling, to measure the amount of torque predicted by the rotor from the gust of wind produced by the speeding train in the tunnel. Being a self-start turbine with no yaw mechanism required the turbine collects air from any direction and converts it into useful power.
