Characteristics of Stirling engine regenerator

The performance of the Stirling engine is influenced by the performance of the regenerator. Over 98% for the regeneration efficiency of the Regenerator must be made with the goal so that the thermal efficiency of the Stirling engine may achieve over 30%. Though the regeneration efficiency is improved as the volume of the regenerator is increased, and as the area of the heating surface is increased, on the other hand as the pressure loss of the inside increases, the output of the engine is lowered. Experiments to examine the characteristics of Stirling engine regenerators are described by the authors.
