Journal ArticleDOI
TL;DR: In this paper, the authors made extensive parametric studies of flow and heat transfer of a viscous fluid contained in a square cavity, where flow is generated by the top horizontal boundary wall, which slides in its own plane at constant speed.

TL;DR: In this article, a review of the body of work dealing with internal recirculating flows generated by the motion of one or more of the containing walls is presented. But the use of direct numerical simulation appears very promising.
Abstract: This review pertains to the body of work dealing with internal recirculating flows generated by the motion of one or more of the containing walls. These flows are not only technologically important, they are of great scientific interest because they display almost all fluid mechanical phenomena in the simplest of geometrical settings. Thus corner eddies, longitudinal vortices, nonuniqueness, transition, and turbulence all occur naturally and can be studied in the same closed geometry. This facilitates the comparison of results from experiment, analysis, and computation over the whole range of Reynolds numbers. Considerable progress has been made in recent years in the understanding of three-dimensional flows and in the study of turbulence. The use of direct numerical simulation appears very promising.
