A Computational Fluid Dynamics Analysis in Mesoscopic Scale on a Type of High Speed Railway Wind Barriers

Railway operators adjust train operation and mount wind barriers as counteraction versus the extreme wind. The evaluation of the extreme wind along railway tracks is a serious topic in this field for the adequate execution of these counteraction.In this paper by focusing on the high speed railway, the effects of a type of wind barriers can be analysis. The solution method for this problem is based on a modern method in computational fluid dynamics that named a Lattice Boltzmann Method. Finally, with calculating the aerodynamic forces and moments coefficients the effects of wind-reduction be determined to appraise the protective effects of railway wind barriers.
