Influence of working fluid on the performance of a standing-wave thermoacoustic prime mover

Theoretical Investigations on Standing Wave Thermoacoustic Prime Mover Using Deltaec

“…At any working pressure, the maximum pressure amplitude achieved is for Ar, followed by N 2 and least for He. The present trend matches with the trend observed during the experiments performed by Hao et.al on standing wave thermoacoustic prime mover [6].…”

“…Maximum onset temperature is for Ar, followed by N 2 and minimum for He. Similar comparison was observed by Hao et.al [6] …”

“…The same trend is followed for He, N 2 and Ar gases, among which helium has the highest value, while nitrogen and argon has almost same value. The trend observed through simulation is similar to the trend obtained by Hao et.al during the experiments [6]. The main reason behind this behaviour is that the resonant frequency depends on the type of the gas and geometry of the prime mover and not on the working pressure [5].…”

Influence of resonator length on the performance of standing wave thermoacoustic prime mover

“…Other examples of the recent publications on standing-wave thermoacoustic prime mover were written by Hao et al [5] and Setiawan et al [6]. The former studied experimentally the influence of difference working gases on the performance of thermoacoustic prime mover while the latter made a numerical study on the effect various compositions of helium-based binary mixture working gases.…”

Experimental studies on thermoacoustic engine with gaseous mixtures

“…al. [6] have studied the influence of working fluid on the performance of a standing-wave type thermoacoustic prime mover using helium-argon mixture. The present work report experimental investigations on performance of standing wave type engine with three gaseous mixtures.…”
