AbstractA modified SIMPLEC method which can solve compressible flows at low Mach number is introduced and used to study thermoacoustic waves induced by a rapid change of temperature at a solid wall and alternating-direction flows generated by thermoacoustic effects in a tapered resonator. The results indicate that the algorithm adopted in this paper can be used for calculating compressible flows and thermoacoustic waves. It is found that the pressure and velocity in the resonator behave as standing waves, and the tapered resonator can suppress high-frequency harmonic waves as observed in a cylindrical resonator.
