摘 要:
回顾了过去lO年在壁湍流和自由剪切流转捩问题的数值研究中取得的重要进展，介绍了数值方法和模式研究方面的进展，以及由此带来的关于转捩理论认识上的进展．对于壁面流动，文中主要介绍了渐进稳定流动中“跨越（bypass）转捩”研究中的各种观点．本文也简要介绍了对感受性和转捩控制方面的研究．[著者文摘]

LOW-DIMENSIONAL MODELING AND NUMERICAL SIMULATION OF TRANSITION IN SIMPLE SHEAR FLOWS
Dietmar;Rempfer
Abstract:
This review describes some of the important developments in the numerical investigation of transition to turbulence in wall-bounded and free shear flows during the past decade. The evolution of numerical techniques and models as well as the advances in our theoretical understanding of the physics of laminar-turbulent transition that were achieved using these tools are described. For wall-bounded flows, particular emphasis is placed on investigations studying various scenarios of “bypass transition” in flows that are asymptotically stable. A brief review of investigations into receptivity and control of transitional flows is included.[著者文摘]
