This book was released on 1987 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to study convective heat transfer in straight and curved rectangular channels of high aspect ratio that approximate plates of infinite extent. Experiments were performed at steady state in the turbulent flow regime with one wall held at a constant heat flux and the opposite wall essentially adiabatic. The effect of curvature induced secondary flow on heat transfer on the concave and convex walls was observed by comparing Nusselt numbers for four different configurations at several different Reynolds numbers. Significant heat transfer enhancement was observed on the concave wall. Correlations for Nusselt number as a function of Reynolds number were calculated for the cases studied.

Book Synopsis Experimental and Numerical Investigation of Turbulent Flow and Heat (mass) Transfer in a Two-pass Trapezoidal Channel with Turbulence Promoters by : Sung Hyuk Oh
Download or read book Experimental and Numerical Investigation of Turbulent Flow and Heat (mass) Transfer in a Two-pass Trapezoidal Channel with Turbulence Promoters written by Sung Hyuk Oh and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments and numerical predictions were conducted to study heat (mass) transfer characteristics in a two-pass trapezoidal channel simulating the cooling passage of a gas turbine blade. Three different rib configurations were tested for the air entering the smaller cross section of the trapezoidal channel as well as the larger cross section of the trapezoidal channel at four different Reynolds numbers of 9,400, 16,800, 31,800, and 57,200. (+) 60[degree] ribs, ( -- ) 60[degree] ribs and 60[degree] V-shaped ribs were attached on both the top and bottom walls in parallel sequence. A naphthalene sublimation technique was used, and the heat and mass transfer analogy was applied to convert the mass transfer coefficients to heat transfer coefficients. Numerical predictions of three-dimensional flow and heat transfer also were performed for the trapezoidal channel with and without 90[degree] ribs tested by Lee et al. (2007). Reynolds stress turbulence model (RSM) in the FLUENT CFD code was used to calculate the heat transfer coefficients and flow fields at Re = 31,800. The results showed that the combined effects of the rib angle, rib orientation, and the sharp 180[degree] turn significantly affected the heat (mass) transfer distributions. The secondary flows induced by the sharp 180[degree] turn and the angled or V-shaped ribs played a very prominent role in heat (mass) transfer enhancements. The heat (mass) transfer enhancements and the pressure drops across the turn for 60[degree] V-shaped ribs had the highest values, then came the case of (+) 60[degree] ribs, and the heat (mass) transfer enhancements and the friction factor ratios for ( -- ) 60[degree] ribs was the lowest. However, comparing ( -- ) 60[degree] ribs with the 90[degree] ribs, ( -- ) 60[degree] ribs produced higher heat (mass) transfer enhancements than the 90[degree] ribs, as results of the secondary flow induced by the ( -- ) 60[degree] ribs. The overall average heat (mass) transfer for the larger inlet cases was always higher than that for the smaller inlet cases in the ribbed trapezoidal channel. Considering the thermal performance comparisons of the (+) 60[degree] ribs, the ( -- ) 60[degree] ribs, and 60[degree] V-shaped ribs for the smaller inlet cases, the highest thermal performance was produced by the ( -- ) 60[degree] ribs, and the 60[degree] V-shaped ribs and the (+) 60[degree] ribs had almost the same levels of the thermal performance since the 60[degree] V-shaped ribs produced the highest heat (mass) transfer enhancement but also produced highest pressure drops. For the larger inlet cases, the (+) 60[degree] ribs produced the highest values, then came the case of the 60[degree] V-shaped ribs, and the thermal performance for the ( -- ) 60[degree] ribs was the lowest. The Reynolds stress model (RSM) showed well flow fields and heat transfer distributions but underpredicted average Nusselt number ratios.

This book was released on 1981 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review is presented of the first year of research performed in an investigation aimed at developing a calculation scheme for predicting general three-dimensional flows in curved passages of circular and square cross-section. The experimental component deals with the implementation and validation of a laser-Doppler velocimeter and associated instrumentation. The numerical component deals with the development of a technique for reducing numerical diffusion in the calculation scheme. An update is provided of the current status of the research. A tentative schedule of work for years two and three is also given. (Author).

This book was released on 2012-11-27 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive reference for engineers and researchers, Gas Turbine Heat Transfer and Cooling Technology, Second Edition has been completely revised and updated to reflect advances in the field made during the past ten years. The second edition retains the format that made the first edition so popular and adds new information mainly based on selected published papers in the open literature. See What’s New in the Second Edition: State-of-the-art cooling technologies such as advanced turbine blade film cooling and internal cooling Modern experimental methods for gas turbine heat transfer and cooling research Advanced computational models for gas turbine heat transfer and cooling performance predictions Suggestions for future research in this critical technology The book discusses the need for turbine cooling, gas turbine heat-transfer problems, and cooling methodology and covers turbine rotor and stator heat-transfer issues, including endwall and blade tip regions under engine conditions, as well as under simulated engine conditions. It then examines turbine rotor and stator blade film cooling and discusses the unsteady high free-stream turbulence effect on simulated cascade airfoils. From here, the book explores impingement cooling, rib-turbulent cooling, pin-fin cooling, and compound and new cooling techniques. It also highlights the effect of rotation on rotor coolant passage heat transfer. Coverage of experimental methods includes heat-transfer and mass-transfer techniques, liquid crystal thermography, optical techniques, as well as flow and thermal measurement techniques. The book concludes with discussions of governing equations and turbulence models and their applications for predicting turbine blade heat transfer and film cooling, and turbine blade internal cooling.
