A Parametric Optimization of a Single Stage Regenerator Using REGEN 3.2

摘要: Regenerative heat exchangers define the crucial design component for high frequency cryocoolers such as Stirling and Pulse Tube refrigerators. To aid in their design, a parametric investigation has been carried out using NIST code REGEN3.2 to optimize single-stage regenerator operating with warm end temperature of 300 K cold that varies between 60 80 K. The matrix choice all calculations is 400-mesh stainless steel. optimization defined by maximizing COP function geometry, mass flow, phase cold-end flow pressure. We have conducted over range 30 — Hz constant average pressure 20 bar ratio 1.2. Regenerator performance—defined net cooling power, losses—is presented along optimized parameters flux, angle order provide convenient charts regenerators.
