• Stability Analysis of Thermoacoustic Oscillation

抄録

Thermoacoustic oscillation is a phenomenon that fluid oscillates spontaneously in a narrow tube with thermal gradient. Thermoacoustic oscillation in a 2D closed tube is studied by numerical calculation of the 2D compressible Navier-Stokes equations. The both sides of tube are hot (T=T_H), and the center is cold (T=T_C). The stability of the thermoacoustic oscillations is analyzed at the different initial pressures. We observe the hystersis phenomena when the initilal pressure is 1.0×10^5Pa. The hystersis phanomenon is not observed when the initilal pressure is 0.175×10^5Pa.
