Abstract:The adjoint optimization method has been well developed and applied in the field of aviation. In this paper, the adjoint method is used to optimize the head shape of a simplified high-speed train, and the feasibility of this method in aerodynamic shape optimization of high speed-trains is discussed. The optimization results show that the aerodynamic drag coefficient of the optimized train is 0.9% lower than that of the original one, while the main feature of the head shape is not changed significantly. The adj… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
