Analysis of FPFD Stirling Cryocooler with Flow Losses

Stirling cryocooler seems to meet the requirement much successfully. These have several advantages over others in the wake of better cooling results with very less maintenance due to absence of valves, development compared with parallel development of Stirling engine prime movers. The free piston free displacer an important type of miniature stirling cryocooler has been favoured for the infrared sensors and electronic applications. Different devices like motor can control piston and displacer indepently. various equations concerning to dynamic and thermodynamic analysis of miniature Stirling cryocooler and linear motor used to drive piston and displacer have been solved with help of numerical methods. To make the analysis more realistic losses have been considered. Flow losses occur in the regenerator. It diverts the performance of Stirling Cryocooler from ideal stirling cryocooler.
