Available in PDF, EPUB and Kindle. Book excerpt: Laminar Flow Forced Convection in Ducts is a sourcebook for compact heat exchanger analytical data. This book describes the analytical solutions for laminar fluid flow and forced convection heat transfer in circular and noncircular pipes, including applicable differential equations and boundary conditions involving velocity and temperature problems of fluid flow. The book also discusses fluid flow—how much power is required to pump fluids through the heat exchanger, as well as the heat transfer—the determination of q" distribution, and the temperature of fluid and walls. The text also analyzes the coolant or heat transfer fluid flows in a nuclear power reactor composed of a bundle of circular section fuel rods located inside a round tube. R.A. Axford addresses fluid flow and heat transfers results for the rod bundle geometry in "Heat Transfer in Rod Bundles." The book also provides an overview and guidelines that can be used for the designer and the applied mathematician. This book is suitable for engineers working in electronics, aerospace, instrumentation, and biomechanics that use cooling or heating exchanges or solar collection systems.

Abstract: Abstract of thesis entitled FORCED CONVECTION IN CURVED DUCTS: MULTIPLICITY AND STABILITY Submitted by Fang LIU for the degree of Doctor of philosophy at the University of Hong Kong in October 2006 Numerical studies are made on fully developed forced convection in slightly / tightly curved ducts of square / rectangular cross-sections, which are encountered in wide applications. The investigation is confined to fully developed flow and heat transfer under peripherally uniform wall temperature. Thermo-physical properties of fluid are taken as the constants. The study focuses on flow bifurcation and stability in curved ducts with different curvature ratios and aspect ratios: slightly curved square ducts, tightly curved square ducts and tightly curved rectangular ducts. Steady bifurcation structures in these curved ducts are obtained. The physical mechanisms and driving forces of the flow structures are discussed. The stability on various branches is determined by direct transient computation on dynamic responses of the multiple solutions. The characteristics of the flow oscillations are revealed by Hilbert spectral analysis. The investigation is divided into three parts according to the curvature ratio and aspect ratio of the curved ducts. In the first part, bifurcation and stability of forced convection in a slightly curved square duct are studied. Six known solution branches are extended to the high Dean number region and four new asymmetric branches are found. As the Dean number increases, fully-developed flows evolve from a stable steady 2-cell solution to a periodic oscillation, another stable steady solution, an intermittent oscillation and a chaotic oscillation. In the second part, bifurcation and stability of forced convection in a tightly curved square duct are studied. Ten solution branches are found, including five asymmetric branches and some sub-branches of the known branches that are new for tightly curved ducts. As the Dean number increases, finite random disturbances lead the flows from a stable steady state to the co-existence of two kinds of periodic oscillations, the co-existence of several kinds of intermittent oscillations, and a chaotic oscillation. In the third part, bifurcation and stability of forced convection in a tightly curved rectangular duct of aspect ratio 10 are investigated. Eleven solution branches are found, seven symmetric and four asymmetric. Ekman vortices are considerably long due to large aspect ratio. As the Dean number increases, finite random disturbances lead the flows from a stable steady state to another stable steady state, a periodic oscillation, an intermittent oscillation, another periodic oscillation and a chaotic oscillation. The mean friction factor and the mean Nusselt number are obtained for all physically-realizable fully-developed flows in these curved ducts. A significant enhancement of heat transfer can be obtained at the expense of a slight increase of flow friction.

This book was released on 1985 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental apparatus has been constructed and tested to examine the convective heat transfer in straight and curved ducts of rectangular cross-section. The channel can be configured with both walls independently heated at a constant heat flux, or one wall at a constant heat flux and the opposite wall adiabatic. Local and average Nusselt numbers can be calculated, and used to evaluate the effect of curvature on heat transfer. Experiments were conducted at steady state of turbulent flow with one wall heated at a constant flux and the opposite wall adiabatic. The heat transfer characteristics of the straight and curved sections, on both the inner and outer walls, were compared. The heat transfer rate of the concave curved wall proved to be enhanced over both the convex curved wall and both straight sections. Keywords: Taylor-Gortler Vortices, Dean Number, Heat Transfer, Turbulent Flow, Rectangular Curved Channel, Rectangular Straight Channel, Secondary Flow, Concave, and Convex.

This book was released on 1980 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental investigations have been conducted to examine the general problem of convective heat transfer in a rectangular cross section channel with both straight and curved passages. The experimental configuration was modeled as infinite parallel plates with one wall at a constant heat flux and the opposite wall adiabatic. The air flow through the channel was heated through the Joulean heating of a wall composed of Temsheet. Liquid crystals applied to the surface of the Temsheet were used to confirm the presence of the Taylor-Gortler vortices. Average Nusselt number mesurements were used to investigate their effect on heat transfer from the curved test section. Experiments were conducted for steady state laminar flow that was hydrodynamically developed and thermally developing. It was confirmed that the Taylor-Gortler vortices enhanced the heat transfer process in the curved section. The experimental data was compared with several analytic studies with good results.

Book excerpt: An experimental investigation was conducted to examine convection heat transfer in a duct of rectangular cross-section, having both a straight and curved flow passage. One wall was kept at a constant temperature, with the opposite wall being adiabatic. Heating of the air flowing in the channel was accomplished through Joulean heating of a wall composed of Temsheet. The experiments were conducted for steady state in Laminar and Transition flows. Development and propagation of the Taylor-Gortler vortices was shown to enhance the heat transfer rate in the curved section as compared to the straight section. (Author).
