Rayleigh-benard Convection: Structures And Dynamics


Book Description

This invaluable book presents a concise but systematic account of the formation of spatial flow structures in a horizontal fluid layer heated from below. Flows of this type, known as Rayleigh-Bénard convection, show important features of behaviour inherent not only in various hydrodynamic-instability phenomena but also in nonlinear pattern-forming processes in other contexts. The book describes the basic methods of investigating convection patterns, and the types of two- and three-dimensional flows, pattern defects, and sequences of convection-regime changes.The author pays special attention to the question of how various factors (mainly reducible to initial and boundary conditions) determine the shapes and sizes of the structures which develop. In this way, the role of order and disorder in flow patterns, as a factor strongly affecting the character of the evolution of structures, is revealed. The presentation emphasizes the physical picture of these phenomena, without excessive mathematical detail.




Rayleigh's Principle and Its Applications to Engineering


Book Description

This text develops Rayleigh's principle in a manner that provides upper and lower estimates of the true value, so that frequencies and critical loads can be determined with close and known degrees of approximation, well within the degree of accuracy usually demanded in engineering problems. Its presentation is accompanied by illustrative examples and rigorous proofs.




Internally Heated Convection and Rayleigh-Bénard Convection


Book Description

This Brief describes six basic models of buoyancy-driven convection in a fluid layer: three configurations of internally heated convection and three configurations of Rayleigh-Bénard convection. The author discusses the main quantities that characterize heat transport in each model, along with the constraints on these quantities. This presentation is the first to place the various models in a unified framework, and similarities and differences between the cases are highlighted. Necessary and sufficient conditions for convective motion are given. For the internally heated cases only, parameter-dependent lower bounds on the mean fluid temperature are proven, and results of past simulations and laboratory experiments are summarized and reanalyzed. The author poses several open questions for future study.




Random Signal Processing


Book Description

This book covers random signals and random processes along with estimation of probability density function, estimation of energy spectral density and power spectral density. The properties of random processes and signal modelling are discussed with basic communication theory estimation and detection. MATLAB simulations are included for each concept with output of the program with case studies and project ideas. The chapters progressively introduce and explain the concepts of random signals and cover multiple applications for signal processing. The book is designed to cater to a wide audience starting from the undergraduates (electronics, electrical, instrumentation, computer, and telecommunication engineering) to the researchers working in the pertinent fields. Key Features: • Aimed at random signal processing with parametric signal processing-using appropriate segment size. • Covers speech, image, medical images, EEG and ECG signal processing. • Reviews optimal detection and estimation. • Discusses parametric modeling and signal processing in transform domain. • Includes MATLAB codes and relevant exercises, case studies and solved examples including multiple choice questions

RAMAS Risk Calc 4.0 Software


Book Description

Many analysts use point estimates and ignore their uncertainty. But we can never be sure about the exact values of numbers based on data. And no practical calculations are without error, even though they may have the appearance of precision. RAMASâ Risk Calc 4.0 Software: Risk Assessment with Uncertain Numbers uses traditional methods such as probability theory and interval analysis and the newest techniques such as probability bounds analysis and fuzzy arithmetic to quantify uncertainty in risk assessments. It creates a convenient environment for computing in which all uncertainties are carried forward automatically. Providing examples in four major application areas, Risk Calc brings sophisticated methods of uncertainty analysis into the reach of anyone who can do arithmetic on a calculator.
