“…Selain eksperimental, simulasi juga sudah dilakukan diantaranya adalah : simulasi berdasarkan hukum thermodinamika ke dua yang menghasilkan pembangitan entropi yang rendah sangat cocok dengan posisi stack dekat dengan tekanan antinode (Piccolo et al, 2013). Simulasi lainnya dengan menggunakan analisis CFD menghasilkan pembangkitan osilasi terjadi pada jarak minimal ¼ dari panjang tabung resonator (Zink et al, 2010). Selain itu simulasi untuk mendapatkan frekuensi yang tepat juga sudah dilakukan dengan menggunakan analisis CFD, dengan kesimpulan bahwa frekuensi 300 hz sudah dapat menghasilkan gelombang akustik dengan kontruksi stack secara paralel dan co-axial.…”

Thermoacoustics refrigeration is considered as one of cooling method, which recently developed. This method can be applied for cooling of foods in particular vegetables. The important components in thermoacoustics refrigeration are: resonator tube, Stack, acoustics driver and working fluid. The advantages of thermoacousic refrigeration include the use of relatively simple components, consequent energy saving, and most importantly thing is environmentally friendly. Recent researches has highlighted the necessity to develop resonator tube and stack concerning shape, design, size and basic material which is used to produce resonator tube and stack. This paper comprehensively reviews the current state of technology to develop shape, design, size, and basic material in the development of thermoacoustics refrigeration. It is concluded that the use of bamboo as basic material can be applied with continuing research of its application may lead to the use of thermoacoustic refrigeration for food and vegetables.

“…A 3D CFD model offers the advantage of providing useful information that can complement the experimental data to give an understanding of the heat transfer and flow physics inside the heat exchangers in oscillatory flow. In the CFD technique to modelling of thermoacoustic engines and refrigerators [22,42,43], the internal elements are often accounted for by using porous media method, where a volume porosity is used to account for the solid fraction, and the pressure loss of the heat exchanger is evaluated using the steady flow relation [14,35]. While this approach reduces the computational effort for modelling the whole thermoacoustic device, it does not give information about the contribution of each constituent element of the system such as the thermal interaction of working fluid with the thermal contact area of the heat exchangers.…”

“…With society's current focus on human impact upon the environment, renewable sources of energy, and the inability for current energy grid systems to fully fill needs for remote and developing civilizations at feasible cost, the development of the thermoacoustic device is a pursuit worth exploring. Compared with traditional refrigerators, thermoacoustic refrigerators (TAR) have advantages of no moving parts, environmental friendliness and potential high efficiency [1].…”

Original scientific paper https://doi.org/10.2298/TSCI170911059LIn this study, a dynamic mesh model was proposed in the light of the actual working condition of an acoustic driver. Moreover, the structural optimization of the stack to improve the performance of thermoacoustic refrigerator was presented using response surface methodology. The analysis of variance was conducted to describe the rationality of regression model and examine the statistical significance of factors. Based on the consideration of parameters interaction, the optimized values of stack parameters suggested by response surface methodology have been predicted successfully. Results showed that optimal stack parameters group could realize the optimal cooling performance. The optimal ratios of stack spacing to stack thickness and stack length to stack position were 3.59-4 and 0.77-1, respectively. This study provides a new method for CFD modeling and optimizing the thermoacoustic refrigerator, which helps to popularize its application.
