Abstract

In computational fluid dynamics programming, meshing quality determines the reliability of the results of numerical calculation. For numerical programming in heat and mass transfer of U-type ground heat exchangers (GHE) in ground source heat pump (GSHP) systems, considering the limitation of the structured grid technology for complex geometric model, unstructured grid technology should be adopted. In this paper, combined with the application and research status at home and abroad, the performance characteristics of the commonly used three kinds of unstructured grid technologies are compared, and the applications of three-dimensional Delaunay grid technology in the related fields are introduced, with emphasis on the research status of the two key problems in the application of this technology, namely boundary consistency and sliver elements. The purpose of this paper is to provide help for the numerical calculation programming of U-type GHE in GSHP systems under coupled heat conduction and advection.
