Experimental study of the temperature variations in a standing wave loudspeaker driven thermoacoustic refrigerator
TL;DR: In this paper, the effect of the stack geometric parameters on the temperature difference across the stack in a standing wave loudspeaker driven thermoacoustic refrigerator was investigated, and the authors provided guidelines for increasing the performance of thermo-acoustic refrigerators, which still lack competitiveness because of their relatively low performance.

An enhanced artificial neural network model using the Harris Hawks optimiser for predicting food liking in the presence of background noise
TL;DR: In this article, the Harris Hawks optimiser (HHO) was used to predict the relative liking of food ratings with higher performance (R2 = 0.70, RMSE= 0.8), as compared to traditional ANNs using feedforward neural networks (FFNNs) and statistical mixed models, which were used to find the threshold level that gives maximum relative food liking ratings for different types of noise.

Design environment for low-amplitude thermoacoustic energy conversion (DeltaEC)
TL;DR: The Los Alamos thermoacoustics code, available at www.lanl.gov/thermoACoustics/, has undergone extensive revision this year, and a Python-based graphical user interface wrapped around that core provides improved usability as discussed by the authors.

Design optimization of thermoacoustic refrigerators
Martin Wetzel,Cila Herman +1 more
TL;DR: The simplified linear model of thermoacoustics - the short stack boundary layer approximation - is implemented into a systematic design and optimization algorithm and serves as an easy-to-follow guideline for the design of therMOacoustic refrigerators.
