Large eddy simulation of the flow field in centrifugal fan and numerical prediction of noise in pipe

Large eddy simulation of the flow field in centrifugal fan and numerical prediction of noise in pipe

<b>[Objectives]</b> In order to predict the vibration noise of centrifugal fan,<b>[Methods]</b> the whole flow field is meshed by the structured grid and the fluctuating force on the impeller surface that varies with time is obtained by using the Large Eddy Simulation(LES)met...
