摘要

Oil atomization is an effective enhanced heat transfer method for single screw compressor, which can make the compression process of single screw compressor be close to the isothermal process, then the working efficiency can be improved. In order to obtain optimal atomization technology effectively, the heat transfer of single screw compressor is analyzed based on fuzzy random wavelet finite element method. Firstly, the relating researching progresses are summarized. Secondly, the heat transfer governing equation of single screw compressor is constructed based on large eddy simulation technology. Thirdly, the heat transfer wavelet finite element model of single screw compressor is established through using Hermitian wavelet function, and then the fuzzy random Hermitian wavelet finite element mode is established based on λ level set theory. Finally, the heat transfer rules of single screw compressor is obtained based on simulation analysis, the effect of atomization on heat transfer of single screw compressor is obtained, results can offer effective theoretical guidance for designing the novel atomization system for single screw compressor.
