The Effect of a Flexible Fiber Cover on Controlling Boundary Layer Flow and Heat Transfer.

Abstract

This report describes the friction and heat transfer characteristics of a solid surface covered with flexible fibers. The work consisted of analysis, numerical simulations, and laboratory experiments. Chapter 1 documents the pressure drop and heat transfer through bundles of parallel cylinders in a domain that has been overlooked, namely, low Reynolds numbers, arrays that are long in the direction of flow such that the flow is hydraulically and thermally fully developed, and cylinders inclined relative to the flow direction. The heat transfer, friction and mechanical (elastic) interaction between an external laminar flow and a solid surface covered by a layer of fibers is documented in Chapter 2. The flow is initially perpendicular to the surface, and the fibers can bend. The effect of fiber bending,
