Abstract

As velocities of high speed trains increase, the loads created by pressure waves ahead and after a train have become an important design criterion. Predictive aerodynamic simulation of these transient phenomena requires an efficient approach to simulate the air flows around vehicles that move through a geometrically complex environment. Here, we describe a Cartesian embedded boundary approach combined with dynamic block-structured adaptive mesh refinement, implemented in our AMROC framework. After validation for a laboratory tunnel simulator, the passage of prototypical train bodies in the open as well as in a realistic tunnel are simulated with high computational efficiency. Ease of the problem setup as well as scalable, quasi-automatic execution confirm the relevance the approach as an efficient computational tool for the investigation of transient train aerodynamics.
