Abstract
Thermo-acoustic refrigerators have recently drawn more attentions because of its eco-friendlier potential to address the
current environmental issues resulting from the use of traditional vapour compression refrigerators. This paper aims at evaluating
different selected ceramic substrates, with square pores, from the point of view of their performance as stack materials in the
design of thermo-acoustic standing wave refrigerators. A 465 mm standing wave thermo-acoustic refrigerator was designed using
numerical approximation provided by a modeling code called DELTAEC (Design Environment for Low-amplitude ThermoAcoustic
Energy Conversion). The design developed focuses, in particular, on the effects of different ceramic substrate
configurations (diameter, length, porosity and position) on the performance of the device. Meaningful comparison on the effect
of the ceramic substrates configuration is provided in order to assess the performance of the device. Guidance on the
identification and the selection of the best geometrical configurations of ceramic substrates are the main contributions of this
work.
