Tornado-like vortices.

Analysis of tornado-like vortices using the DES turbulence model, coupling aero-acoustic phenomenon (acousticFoam). Analysis of flow around a building in a tornado generator and acoustic analysis inside the building Sound transmitted through glass.

Introduction

• This is an example of indoor acoustic analysis in which the DES analysis around the building in the tornado generator and the pressure fluctuation on the window glass obtained by the analysis are coupled using .
• Deformation of window glass is obtained by structural analysis (Kirchhoff Shell model) using the finite area method.
• Acoustic analysis is performed by solving the wave equation using the finite volume method.
• The analysis method is to first perform DES analysis around the building inside the tornado generator, acquire the pressure distribution time series data of the target window glass, and use the data as input for the finite area method to solve the deformation of the window glass. Acoustic analysis in the room is performed using the vibration result due to the deformation as the boundary condition of the wave equation.
