Although the widespread
introduction of numerical tools and the CFD models have improved the
design methodology of thermoacoustic coolers and eased optimization
of such units, high computational costs vitally limit their
application in parametric analyses of thermoacoustic devices. Thus,
experimental investigation remains essential field of research,
considering design of such units. In the paper, the design and
construction of an experimental setup, dedicated to perform an
extensive multiparametric analyses on compact thermoacoustic devices
with varying characteristic parameters, is discussed in detail. A
complete design path, beginning with general consideration, with
further detailed dimensioning and selection of market-available
parts, ending with installation of control and data acquisition
equipment, is described. Initial testing of the device, performed
both computationally at the design stage and experimentally after the
final setup assembling, is discussed as well. The results of the
tests demonstrated ability to observe the variability in the
operational parameters of the cooler following change in number of
environmental and constructional parameters. The data acquired
indicated vital importance of the stack porosity and frequency of
the acoustic wave on performance of the thermoacoustic device, which
corresponds to the data presented in the literature.
