Abstract
Stirling engine is a hot air engine was invented by a
gentleman called Robert Stirling in 1816.Its theory of operation
depends on two levels of temperature. The regenerator is the
important component in Stirling engine where it absorbs the
heat [Tom the working gas when the gas flows from the hot side
to the cold side and releases heat during the reverse process.
The past researches used spring mesh, stacked wire gauzes,
wire netting and sponge metal as regenerators. The present
work introduces a new design of regenerator in the form of wire
rope. The specimens used in the experimental part of this work
were made of the electric cables commercially available. The
wire rope was easy to prepare, easy control of the porosity and
good handling. In addition to the above, the flow loss of wire
rope regenerator is less than that of wire mesh regenerator.
The main scope of this research reports the results of
pressure DROP measurement of wire rope regenerator
undergoing oscillating and steady flows. Two test rigs were
designed and installed in this research. The first test rig was
used for measuring the pressure DROP through the regenerator in
\J
case of steady flow. Differential pressure module matched with
digital meter was used to measure the pressure DROP in the
specimens. The high air now rate was measured by an orifice
plate and by a Ll-rnanorncter while the small air flow rates were
measured by an air rotameter. The friction factor and Reynolds
number could be calculated and the relation between them was
plotted for each specimen. The comparison between wire ropc
pressure DROP and wire mesh pressure DROP was carried out
