Vortical flow structure of thermoacoustic oscillations in a closed tube

Spontaneous thermoacoustic oscillations of a gas in a closed cylindrical tube are studied. Numerical simulations of the flow field in the tube on which a temperature gradient along the axis is imposed are performed by solving the axisymmetric compressible Navier-Stokes equations. The wall temperatur...
