A numerical model of a thermoacoustic engine was developed. The model can be used for the analysis and design of thermoacoustic engines. Effects of heater power and mean pressure of the working gas on the temperature difference of hot and cold heat exchangers, pressure amplitude and frequency were investigated. The temperature difference between the hot and cold heat exchangers increases as the heater power increases, and decreases as mean pressure increases. The amplitude of the first-order pressure increases with heater power and mean pressure. Frequency is independent with heater power, but decreases as mean pressure increases.
