Interfacial Phenomena and the Marangoni Effect


Book Description

Marangoni (1878), provided a wealth of detailed information on the effects of variations of the potential energy of liquid surfaces and, in particular, flow arising from variations in temperature and surfactant composition. One aspect of this science is seen today to bear on important phenomena associated with the processing of modern materials. The role of the basic effect in technology was probably first demonstrated by chemical engineers in the field of liquid-liquid extraction. Indeed, phenomena attributable to Marangoni flows have been reported in innumerable instances relevant to modern technologies, such as in hot salt corrosion in aeroturbine blades; the drying of solvent-containing paints; the drying of silicon wafers used in electronics; in materials processing, particularly in metallic systems which have been suspected to demonstrate Marangoni flows.




Marangoni and Interfacial Phenomena in Materials Procesessing


Book Description

Convection in fluids associated with gradients in surface tension, whether associated with temperature or concentration gradients, has been studied for over a century. There has been a growing awareness of their significance to a wide range of materials processes. This meeting has brought together leading scientists who are elucidating the fundamental aspects of the Marangoni effect, with those with an industrial interest in exploiting the Marangoni effect to optimize material processing in diverse industrial sectors. The significance of the effect in liquid metal processing (such as in steel making, welding, coating, secondary melting) is shown to be particularly strong and to be a major factor in guiding the approaches to industrial control of these processes. It is hoped that these proceedings will stimulate interest in applying these concepts to other processes where they undoubtedly play an important role. Book jacket.




Interfacial Physical Chemistry of High-Temperature Melts


Book Description

This English translation of a well-known Japanese book covers interfacial physicochemistry in materials science, especially for iron- and steelmaking processes. Interfacial Physical Chemistry of High-Temperature Melts bridges the gap between the basics and applications of physicochemistry. The book begins with an overview of the fundamentals of interfacial physical chemistry and discusses surface tension, describing the derivation of important equations to guide readers to a deep understanding of the phenomenon. The book then goes on to introduce interfacial properties of high-temperature melts, especially the Marangoni effect, and discusses applications to materials processing at high temperature focusing on recent research results by the author and the co-workers. This book is aimed at researchers, graduate students, and professionals in materials processing. Video clips of in-situ observation including experiments under microgravity condition and x-ray observation are available for download on the publisher's website to allow for a deeper understanding.




Wettability and Interfacial Phenomena


Book Description

Wettability at the solid/liquid interface, its dynamics, tunability, the influence of operating parameters, surface and interfacial phenomena play an increasingly significant role in a wide variety of applications, for example, material processing, nanotechnology, oil recovery, oil spills, chemical leaching, water management, and disease transmission. Although a mature field, it is experiencing dramatic developments on several fronts with emerging applications in new fields. This book presents a collection of eight chapters on nanoscale wetting phenomena, oil extraction from reservoir rocks, the role of coatings, particle morphology, surface roughness and viscosity in metal processing, and practical applications of superhydrophobic behaviour in cell culturing, isolation, anti-icing, anti-reflective and anti-corrosion coatings in the transportation and optical devices fields.




Physics of Fluids in Microgravity


Book Description

In a microgravity experiment, the conditions prevalent in fluid phases can be substantially different from those on the ground and can be exploited to improve different processes. Fluid physics research in microgravity is important for the advancement of all microgravity scients: life, material, and engineering. Space flight provides a uniqu
