Краткое описание

Regenerators as heat exchangers of cryocoolers are widely used low temperature equipment. The energy efficiency of cryocoolers and their power consumption are dependent on the parameters and material properties of the regenerator. This article examines the method of modeling of regular packing structures using the theory of minimal surfaces in the field of cryogenic engineering. This research can be useful for other applications, such as integration of the porous structures with biological tissues, leading to innovative medical technologies.
The variants of geometry and hydrodynamicsmodeling in the channels of a porous structure at 3D modeling concerning the design of an effective porous structure for regenerators of micro-cryocoolers are considered. The present research is focused on the constructing of finite-difference computational grids for two types of corpuscular porous structures: structures of spherical elements and wire mesh. A method to define hydraulic resistance Δp of the porous structure using the package CFD-analysis ANSYS Fluent version 18.0 is offered.
