Abstract:
A thermoacoustic device, which is operated using
thermoacoustic phenomena, has attracted a great deal of
attention as an application of renewable heat energy. For a
practical application of such device, the correct estimation of
thermoacoustic properties is quite important. In the present
study, a numerical simulation for thermoacoustic device is
performed using computational fluid dynamics (CFD), and the
thermodynamic properties are investigated. The results include
the temperature flow field and heat flux on the wall. The actual
thermoacoustic phenomena are accompanied with nonlinear
effects. In order to estimate those effects, the numerical linear
analysis is also carried out. Through the comparison of the
results of CFD and linear analysis, the linear and nonlinear
characteristics of heat transfer in the thermoacoustic device are
discussed.
