Abstract
Numerical simulation of heat and fluid flow has been performed to clarify the thermal conditions using for transient one-dimensional numerical simulations of a miniature thermoacoustic oscillator. Transient one-dimensional equations of continuity, momentum and energy were solved utilizing a TVD scheme. A simple physical model was used for the numerical simulation. As a result, it was found that the consideration of the other thermal conditions with the input heat conditions that heat is transferred from a heater to working gas and to walls for the numerical analysis of a thermoacoustic oscillator is necessary because both of the behaviors of temperature change and pressure amplitude are different from the experimental results.
