CFD Analysis and Optimization of Maglev Train for High Speed Corridor Project

Abstract

Magnetic levitation (Maglev) a new developed technology in recent days has been applied in various countries. Indian Government has taken initiative to implement High Speed Train in India. For this High-Speed corridor project, a Maglev model is proposed with Computational Fluid Dynamics (CFD) analysis. Ansys Fluent tool is used to determine the aerodynamic performances such as, drag force, pressure distribution and flow visualization. Here the boundary condition is used as inlet velocity and outlet as pressure. The obtained results from fluent analysis are coupled to the structural analysis to find the possible stresses. Fluid structure Interaction (FSI) is used to couple the fluent with structural analysis so that the total deformation also gets. At 30m/s speed the total pressure 620 Pa is obtained. This total pressure is given to structural analysis as load as a result the equivalent stress is 0.42879 MP is obtained which is under the permissible limit of material which assigned to the proposed model. Wind tunnel experiment is carried out to determine the drag force theoretically.
