Vortex structures and aeroacoustic performance of the flow field of the pantograph

Journal of Sound and Vibration, 2018
Abstract The object of study in this paper is the Faiveley CX-PG pantograph. We first used the large-eddy simulation (LES) model to simulate the surrounding fluctuating flow field. We then identified the vortex structures in the flow field of the pantograph via the Q criterion, and performed a Fourier transform on the fluctuating pressure. We finally

Optimization of a regenerative blower to enhance aerodynamic and aeroacoustic performance

Journal of Mechanical Science and Technology, 2016
A multi-objective optimization was performed to simultaneously enhance the aerodynamic and aeroacoustic performance of a side channel-type regenerative blower. The aerodynamic characteristics of the regenerative blower were investigated numerically using threedimensional steady and unsteady Reynolds-averaged Navier-Stokes analysis with a shear stress ...

On Predicting Aeroacoustic Performance of Ducts with Broadband Noise Source Models

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">A numerical method of predicting aeroacoustic performance of HVAC ducts is presented here. The method comprises of two steps. First, the steady state flow structure inside a duct is simulated using computational fluid dynamics (CFD). A k-epsilon based turbulence model is used.

Design Method of the Sirocco Fan Considering Aeroacoustic Performance Characteristics

Journal of Fluid Machinery, 2010
A design method of Sirocco fan is developed for constructing 3-D impeller and scroll geometries, and for predicting both the aerodynamic performance and the noise characteristics of the designed fan. The aerodynamic blading design of fan is conducted by blade angle, camber line determinations and airfoil thickness distribution, and then the scroll ...
