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.

Covers both the fundamentals of software design and modern design methodologies Provides comparisons of different development methods, tools and languages Blends theory and practical experience together Emphasises the use of diagrams and is highly illustrated

WHAT IS THIS BOOKABOUT7 In recent times real-time computer systems have become increasingly complex and sophisticated. It has now become apparent that, to implement such schemes effectively, professional, rigorous software methods must be used. This includes analysis, design and implementation. Unfortunately few textbooks cover this area well. Frequently they are hardware oriented with limited coverage of software, or software texts which ignore the issues of real-time systems. This book aims to fill that gap by describing the total software design and is given development process for real-time systems. Further, special emphasis of microprocessor-based real-time embedded systems. to the needs WHAT ARE REAL-TIME COMPUTER SYSTEMS? Real-time systems are those which must produce correct responses within a definite time limit. Should computer responses exceed these time bounds then performance degradation and/or malfunction results. WHAT ARE REAL-TIME EMBEDDED COMPUTER SYSTEMS? Here the computer is merely one functional element within a real-time system; it is not a computing machine in its own right. WHO SHOULD READ THIS BOOK? Those involved, or who intend to get involved, in the design of software for real-time systems. It is written with both software and hardware engineers in mind, being suitable for students and professional engineers.

A theoretical study has been made to estimate the potentialities of a constricted-arc gas heater in which the wall of the constrictor tube is transpiration cooled. By use of an integral form of the energy equation, it is found that the mass-average enthalpy reaches a maximum value in a distance, in tube diameters, of about half the ratio of the initial axial mass flux to the radial mass flux of the transpiring gas. When compressibility effects are small, the maximum is an asymptotic state. For this state the conservation equations are reduced to ordinary differential equations which are solved numerically for the case of hydrogen at atmospheric pressure. The graphical results show the relationship between blowing rate, power input, wall temperature, peak temperature, average enthalpy, electric field and current, and also distributions of various dependent variables. The range in which the solution is valid is determined from calculations of axial and radial pressure variations, Mach number, axial Reynolds number, and of the minimum blowing rate. From these considerations one can predict that a peak temperature of about 60,000K should be obtainable, but that the maximum mass-average enthalpy will be about the same as that obtainable from a water-cooled arc. Some results are presented to show the sensitivity of the solution to changes in the electrical conductivity, the radiated power and the radial velocity profile.

This volume deals with the practical implementation of peripheral interface systems in real-time, "real-world" microcomputer controllers. Sure to be a title added to many reference libraries.

An experimental investigation into the heat-transfer characteristics of two-component, two-phase flows about a cylinder is described. Heat-transfer coefficients were measured at various positions around the periphery of the cylinder with systematic variations of cooling stream velocity, droplet size, and liquid-gas mass-ratio. The two-component cooling stream was a mixture of water droplets in air. An analysis of the heat-transfer characteristics over the front half of the cylinder, where the bulk of the heat transfer takes place, has been carried out for a simplified model. In this model, the air is assumed to be incompressible, and bouncing of droplets from the surface of the cylinder has been ignored. It has been found that this analysis gives some valuable insight into the relative importance of the various mechanisms which contribute to the over-all heat transfer. Both the experimental and the analytical results show that, in general, significant increases in heat transfer are obtained over that which would be obtained from a single-component gaseous cooling fluid.
