Large Eddy Simulation of the Flow around one Single-Stacked Container Freight Wagon
Paper i proceeding, 2012

In this work a time-dependent numerical simulation of the flow around a single stand- ing container wagon model is presented. The model consists of a 11.8m long con- tainer placed on the wagon. The model includes some geometrical details such as wheels and other undercarriage roughness. The Reynolds number in the study is 100,000 based on the width of the container. The simulation method used is the Large Eddy Simulation technique. The forces and the flow field are averaged in time and the re- sults thereof are presented in the paper.
