Thermoacoustic Refrigerators use acoustic power for generating cold of refrigerators based on thermoacoustic technology is a novel solution to the present. In this paper the design of thermoacoustic refrigerators, using the linear thermoacoustic theory, development procedure of a thermoacoustic refrigerator . Heat Mass Transfer. DOI /sy. Maximum cooling and maximum efficiency of thermoacoustic refrigerators. L. K. Tartibu.

Part of the Nato ASI Series book series NSSE, volume Abstract During the past fifteen years heat transfer in oscillatory flows has become the subject of increasing interest in the engineering community. Applications of oscillatory flows include, for example, the cooling of electronic equipment or alternative, environmentally safe refrigeration technologies, such as thermoacoustic refrigeration, pulse tubes or Stirling refrigerators. Important components of these refrigerators are their heat exchangers. In such devices the working fluid is subjected to oscillatory forcing which is a key part of the process, as opposed to situations where oscillations are generated with the aim to enhance heat transfer. Heat transfer in oscillatory, and often compressible, flows has not yet been completely understood, and the lack of design methodologies for heat exchangers in such flows is one reason that efficiencies of these devices are limited.

Nouh et al. Nearly all of the thermoacoustic refrigerators in existence are driven by electromagnetic loud speakers. However, the performance of electromagnetic loudspeakers is greatly diminished at high frequencies. For this reason, piezoelectric drivers have been used for high frequency applications of thermoacoustic refrigeration [10—12]. The conversion of electrical pulses into mechanical vibrations drive the acoustic pulsations along the resonator which are needed to create the temperature difference across the ends of the stack.

Avoiding electromagnetic drivers may also be required for applications involving magnetic sensitive equipment. Unlike their electromagnetically driven counterparts, numerical and experimental models for PDTARs are lacking.

A mathematical model is developed for this system and this model is validated experimentally in order to provide a tool for designers to use with applications requiring piezoelectric actuation. The current paper investigates whether the same concept can be extended to thermoacoustic refrigerators in an attempt to enhance their cooling outcome.

The paper is organized in 6 sections. Following the brief introduction outlined in Section 1, a quick mathematical overview of the equations governing piezo-driven thermoacoustic refrigerators, taking into account the coupling between the piezoelectric speaker and the acoustic resonator, is presented in Section 2. The actual performance of the PDTAR experimental prototypes in comparison with the developed models is presented in Section 5.

Finally, the conclusions are summarized in Section 6.
