摘要

摘要: 边界层流动转捩的预测与控制一直是流体力学研究中的一个重要问题. 三维边界层流动工程中十分常见, 而横流失稳是导致三维边界层流动转捩的主要原因. 本文综述了近些年来三维边界层失稳和转捩方面的研究概况. 从机理上讨论了横流扰动的感受性、首次失稳、二次失稳和转捩控制等方面的研究进展. 在数值计算方面, 简要概述了线性稳定性理论、非线性稳定性理论和直接数值模拟方法在横流失稳和转捩方面的应用.本文对横流失稳研究当前存在的问题进行了讨论, 对今后研究的发展趋势作了相应展望.

Abstract: Boundary layer transition prediction and control is one of the most ambitions topics of research activities in aerodynamics. The crossflow instability of a three-dimensional boundary layer is a main factor affecting the laminar transition. The current understanding of 3-d boundary-layer transition is reviewed. Recent advances in receptivity, primary instability, secondary instability and transition control of crossflow boundary layer flows are discussed. Challenges about compressible crossflow transition remain and prospects are presented as well.
