Numerical Modeling Procedure for Micromachined Cryogenic Cooler Elements Using ANSYS Fluent Software and Viscous Flow in a Small-Diameter Channel with Heat Transfer as an Example

Abstract

Initial results from a comparative analysis of hydrodynamic and heat-transfer data for the channel connecting compression and displacement volumes (thoroughfare) are attained by using semiempirical criterial functions and finite-element simulation with various RANS turbulence models for a reversed Stirling cryocooler. The model for the numerical experiment is created using the ANSYS Fluent CFD software.
