Numerical Simulation of Aerodynamic Noise for High-Speed Train in Exterior Flow Field
摘要
Abstract
Based on Reynolds averaged numerical simulation,we had the steady exterior flow field of high-speed train with FLUENT software and analyzed the surfaces’noise source of high-speed train in Broad Noise Source Model with FLUENT software.Secondly,the fluctuating pressure on the surface of high-speed train was calculated and obtained by analyzing the external flow field using large eddy simulation.And we transformed the time domain into the frequency domain through the fast Fourier transforming.Some aerodynamic noise characteristics for high-speed train were received by the analysis of pulsating pressure level power spectrum.关键词
