This paper is dedicated to the generations of students who honored me by their willingness to join their hearts and minds with mine, and to my wife who taught all of us that it is heart, rather than mind, that makes the world go ’round. The paper showcases a highly personalized style of research characterized by intense human involvement and a minimum of material resources, and exemplifies the notion that “less is more.” The technical content of the paper is a collection of themewise-related pieces of research, all of which have to do with fluid flows which do not follow the contour of the bounding wall(s) and with the related heat transfer ramifications. Two classes of such flows are considered. In one, the fluid is acted on by forces directed normal to the wall, causing lift-off. The other non-wall-adhering class of flows to be considered is separated flows.
