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 |
