Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this project is study convective heat transfer and fluid-mechanics in a concavely curved turbulent boundary layer. The objective is to identify the mechanisms whereby concavity increases surface heat transfer. Progress during the past year has centered on the recently added goal of studying the combined effects of moderate levels of grid-generated turbulence and concave curvature. Overall results from the fluid-mechanics section of the project are that grid-generated turbulence increases the skin friction, but does not alter the near-wall mean velocity scaling or the near-wall levels of the velocity fluctuations. The heat transfer measurements are showing that the Stanton number is increased by the grid-generated turbulence with the combined effects of curvature and the additional turbulence producing the largest increase. Keywords: Heat transfer, Turbulent boundary layers, Adaptive grids.

This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of transverse convex surface curvature on turbulent boundary layer flow and heat transfer over circular cylinders, and on fully developed turbulent flow and heat transfer in concentric annular ducts with smooth surfaces are studied both analytically and experimentally. The analytical results are obtained through a turbulence model based on the variable von Karman's constants, $\rm\kappa\sb{i}$, proposed for the first time in the present study. A computer program is developed for calculation of the desired momentum and thermal characteristics. A numerical calculation using the standard k-$\varepsilon$ turbulence model, with a modified procedure is also carried out. It is assumed that the thermodynamic fluid properties are independent of temperature. An experimental study is conducted to study the effect of the transverse convex surface curvature of the core tubes both on fully developed turbulent flows and heat transfer in concentric annular ducts. Air is used as the working fluid. Three annuli having different radii of the inner cores, R$\rm\sb{i}$ = 3.98 mm, 8.57 mm, and 16.7 mm, with a fixed radius ratio of $\alpha$ = 0.3, are used over a range of the Reynolds number between about 20,000 and 60,000. The inner cores are heated electrically to provide constant heat fluxes throughout the test sections and are instrumented for the temperature and power measurements. The outer tubes are insulated to minimize the leakage of heat. In the case of the experimental study for turbulent boundary layer flows and heat transfer on circular cylinders, the experimental data of Willmarth et al. (31) and Kim and Lee (45, 46) are recompiled for the present study. It is seen that both the friction coefficient and heat transfer increase with decreasing value of the inner core radius of concentric annuli and the radius of circular cylinders, R$\rm\sb{i}$ It is concluded that, while the effect of transverse concave curvature on fluid flow and heat transfer is negligible, that of transverse convex curvature is rather significant.

Available in PDF, EPUB and Kindle. Book excerpt: New Edition Now Covers Shock-Wave Analysis An in-depth presentation of analytical methods and physical foundations, Analytical Fluid Dynamics, Third Edition breaks down the "how" and "why" of fluid dynamics. While continuing to cover the most fundamental topics in fluid mechanics, this latest work emphasizes advanced analytical approaches to aid in the analytical process and corresponding physical interpretation. It also addresses the need for a more flexible mathematical language (utilizing vector and tensor analysis and transformation theory) to cover the growing complexity of fluid dynamics. Revised and updated, the text centers on shock-wave structure, shock-wave derivatives, and shock-produced vorticity; supersonic diffusers; thrust and lift from an asymmetric nozzle; and outlines operator methods and laminar boundary-layer theory. In addition, the discussion introduces pertinent assumptions, reasons for studying a particular topic, background discussion, illustrative examples, and numerous end-of-chapter problems. Utilizing a wide variety of topics on inviscid and viscous fluid dynamics, the author covers material that includes: Viscous dissipation The second law of thermodynamics Calorically imperfect gas flows Aerodynamic sweep Shock-wave interference Unsteady one-dimensional flow Internal ballistics Force and momentum balance The Substitution Principle Rarefaction shock waves A comprehensive treatment of flow property derivatives just downstream of an unsteady three-dimensional shock Shock-generated vorticity Triple points An extended version of the Navier‒Stokes equations Shock-free supersonic diffusers Lift and thrust from an asymmetric nozzle Analytical Fluid Dynamics, Third Edition outlines the basics of analytical fluid mechanics while emphasizing analytical approaches to fluid dynamics. Covering the material in-depth, this book provides an authoritative interpretation of formulations and procedures in analytical fluid dynamics, and offers analytical solutions to fluid dynamic problems.
