Review of mathematical models for leakage in scroll compressors
摘要
Abstract
Leakage research in scroll compressors is crucial for their theoretical simulation,structural design,and performance analysis.This paper introduces two main leakage pathways in scroll compressors,reviews research achievements by domestic and international scholars,analyzes and compares leakage calculation models based on 3D CFD and 1D simulation,and discusses property mixing methods when considering lubricating oil.For 3D leakage calculations,studies mostly use software such as Fluent,CFX,PumpLinx,and Simerics MP+,primarily focusing on performance optimization or impact through structural modifications;1D calculations mainly employ modified nozzle models,parallel plate flow models,incompressible viscous flow models,etc.,emphasizing performance improvement and model prediction accuracy,with most models requiring experimental correction and having specific applicable operating ranges.The research results indicate that clearance size significantly affects leakage outcomes,while channel shape,roughness,and lubricating oil also influence leakage behavior;when considering lubricating oil,the working fluid and oil are typically treated as a homogeneous mixture.Regarding sealing method improvements,theoretical and experimental research can be conducted on novel flow structures.In terms of different research approaches,future 3D CFD simulations could develop towards systematization,fluid-structure coupling,and integration with reverse engineering and artificial intelligence;1D simulations should incorporate heat transfer and variable working fluid conditions,further optimizing leakage predictions by combining Fanno flow models,oil-containing conditions,and two-phase flow models.This study can provide references for the development and performance optimization of scroll compressors.关键词
