Fluid flow around bluff bodies occurs in numerous fields of science and engineering, such as flows pass vehicles, cables, towers and bridges.These flows have been studied experimentally and numerically frisky for the last several decades.The investigation of flow around high-speed trains is an important application of bluff bodies.Fluid flow, aerodynamic OtherRestraints forces and moments, separation and wake region have been studied for the last several decades.This paper brings together a comprehensive review of the research on air flow around high-speed trains and their impacts.
