Computational design and aerodynamic optimization of locomotive nose shapes J.L. Peters Department of Aerodynamics and Aeroacoustics, Krauss-Maffei Verkehrstechnik GmbH, Munich, Germany Abstract A Computational Fluid Dynamics code is used to calculate and optimize the head pressure pulse of locomotives. Comparison of calculated results with results of full-scale and wind tunnel tests demonstrate the validity of the method. The main results of a systematic investigation of the effect of the geometrical parameters of the nose of locomotives on their pressure pulse alongside the track are given. 1 Introduction Following the example of French and German Railways, several other European railway companies have included maximum authorized head pressure pulse amplitudes in their specification for new rolling stock. The reliable prediction of this physical phenomenon at the earliest possible stage of a new project has therefore become paramount to any European locomotive or leading car bu
