最小熵增准则在激波/边界层干扰分析中的应用
Application of minimum entropy production principle to analysis of shock wave/boundary layer interactions
摘要
Abstract
Shock Wave/Boundary Layer Interactions(SWBLI)are prevalent in both internal and external flow fields of high-speed vehicles,characterized by multi-scale,nonlinear,and unsteady phenomena.These interactions lead to significant local increases in heat flux and pressure,which impact the flow quality and structural integrity of the vehicle.This study provides a comprehensive investigation into the shock structure characteristics and wall pressure rise be-havior induced by SWBLI.By analyzing the shock structures in several representative scenarios,the underlying mechanisms of such complex flows are explored.Firstly,the progress of key theoretical models,including the inviscid shock reflection theory,free interaction theory,and minimal viscous dissipation,is reviewed.Subsequently,a com-parative analysis is made between two predominant modeling approaches:one is based on boundary layer structures,and the other is based on shock wave interaction structures.Finally,the application of the principle of Minimum En-tropy Production(MEP),an extension of the second law of thermodynamics,to SWBLI-related complex flow fields is discussed.The results indicate that the MEP principle offers substantial advantages when applied to SWBLI flows in-volving separation.The results obtained using the principle exhibits a high degree of agreement with experimental re-sults in analysis and prediction of both shock structure and pressure rise,thus providing a novel perspective for ad-dressing the fundamental scientific challenges associated with SWBLI.关键词
