Download or read book Mathematical Models of Viscous Friction written by Paolo Buttà and published by Springer. This book was released on 2015-02-05 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this monograph we present a review of a number of recent results on the motion of a classical body immersed in an infinitely extended medium and subjected to the action of an external force. We investigate this topic in the framework of mathematical physics by focusing mainly on the class of purely Hamiltonian systems, for which very few results are available. We discuss two cases: when the medium is a gas and when it is a fluid. In the first case, the aim is to obtain microscopic models of viscous friction. In the second, we seek to underline some non-trivial features of the motion. Far from giving a general survey on the subject, which is very rich and complex from both a phenomenological and theoretical point of view, we focus on some fairly simple models that can be studied rigorously, thus providing a first step towards a mathematical description of viscous friction. In some cases, we restrict ourselves to studying the problem at a heuristic level, or we present the main ideas, discussing only some aspects of the proof if it is prohibitively technical. This book is principally addressed to researchers or PhD students who are interested in this or related fields of mathematical physics.

Download or read book The Boundary Layers in Fluids with Little Friction written by H. Blasius and published by . This book was released on 1950 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vortices forming in flowing water behind solid bodies are not represented correctly by the solution of the potential theory nor by Helmholtz's jets. Potential theory is unable to satisfy the condition that the water adheres at the wetted bodies, and its solutions of the fundamental hydrodynamic equations are at variance with the observation that the flow separates from the body at a certain point and sends forth a highly turbulent boundary layer into the free flow. Helmholtz's theory attempts to imitate the latter effect in such a way that it joins two potential flows, jet and still water, non-analytical along a stream curve. The admissibility of this method is based on the fact that, at zero pressure, which is to prevail at the cited stream curve, the connection of the fluid, and with it the effect of adjacent parts on each other, is canceled. In reality, however, the pressure at these boundaries is definitely not zero, but can even be varied arbitrarily. Besides, Helmholtz's theory with its potential flows does not satisfy the condition of adherence nor explain the origin of the vortices, for in all of these problems, the friction must be taken into account on principle, according to the vortex theorem.
Download or read book Mitigation Of Hydrodynamic Resistance Methods To Reduce Hydrodynamic Drag written by Marc Perlin and published by World Scientific. This book was released on 2014-11-18 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text presents the state of the art in friction drag/resistance reduction technologies for BODIES and crafts operating in liquids at and beneath the free surface. It is useful for professionals with backgrounds in advanced fluid dynamics as well as by academics teaching introductory graduate courses in this area. Active control of resistance will include a discussion of friction reduction, for example through the injection of gas that can form air layers and polymers that initially reside adjacent to the hull, including the use of partial and super cavities. The book discusses passive resistance control achieved through changes in the overall hull shape and appendages, including the application of lifting bodies, bulbous bows, and stern flaps. It also addresses passive reduction of skin friction through the application of hull coatings and other elements of hull husbandry.
Download or read book Control of Machines with Friction written by Brian Armstrong-Hélouvry and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is my ambition in writing this book to bring tribology to the study of control of machines with friction. Tribology, from the greek for study of rubbing, is the discipline that concerns itself with friction, wear and lubrication. Tribology spans a great range of disciplines, from surface physics to lubrication chemistry and engineering, and comprises investigators in diverse specialities. The English language tribology literature now grows at a rate of some 700 articles per year. But for all of this activity, in the three years that I have been concerned with the control of machines with friction, I have but once met a fellow controls engineer who was aware that the field existed, this including many who were concerned with friction. In this vein I must confess that, before undertaking these investigations, I too was unaware that an active discipline of friction existed. The experience stands out as a mark of the specialization of our time. Within tribology, experimental and theoretical understanding of friction in lubricated machines is well developed. The controls engineer's interest is in dynamics, which is not the central interest of the tribologist. The tribologist is more often concerned with wear, with respect to which there has been enormous progress - witness the many mechanisms which we buy today that are lubricated once only, and that at the factory. Though a secondary interest, frictional dynamics are note forgotten by tribology.

Download or read book Elasto Hydrodynamic Lubrication written by D. Dowson and published by Elsevier. This book was released on 2014-07-18 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elasto-Hydrodynamic Lubrication deals with the mechanism of elasto-hydrodynamic lubrication, that is, the lubrication regime in operation over the small areas where machine components are in nominal point or line contact. The lubrication of rigid contacts is discussed, along with the effects of high pressure on the lubricant and bounding solids. The governing equations for the solution of elasto-hydrodynamic problems are presented. Comprised of 13 chapters, this volume begins with an overview of elasto-hydrodynamic lubrication and representation of contacts by cylinders, followed by a discussion on equations relevant to lubrication, including the Reynolds equation. The reader is then introduced to lubrication of rigid cylinders; the importance of film thickness in highly loaded rigid contacts; the elasticity of solids in contact; and the theory of elasto-hydrodynamic lubrication. Subsequent chapters focus on apparatus and measurements of film thickness and film shape; friction and viscosity; and lubrication of gears and roller bearings. This book will be of interest to tribologists.

Download or read book Tribology written by James M. Watterson and published by Momentum Press. This book was released on 2019-01-16 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the types of seals and bearings that are commonly found in most rotating and moving machinery, including how they are designed, how they work and what can be done to ensure that they continue maintain proper lubrication and successful operation. Tribology is the scientific and engineering study of friction, and in common practice; it most often involves the control and reduction of friction. This is particularly critical to the successful and continued operation of moving parts. The author discusses the critical lubrication issues dealt with in gears and gear boxes, focusing on specific types of mechanical seals, including compression seals, hydrodynamic seals, hydrostatic seals, and mechanical face seals. Dr. Watterson also introduces the reader to the major types of bearings, including roller bearings, ball bearings and various types of sealed bearing systems, and their maintenance and lubrication requirements.

Download or read book Friction Reduction by Algal and Bacterial Polymers written by Paul R. Kenis and published by . This book was released on 1971 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-chain polymers from many seaweeds, microscopic algae, and bacteria have been demonstrated to reduce turbulent-flow friction in water. In the investigation all water samples tested from inland and marine sources gained friction-reduction ability when enriched with sugar, as a consequence of polysaccharide synthesis by bacteria. Biological polymers, therefore, are the probable cause of the unexplainable variations in hydrodynamic test facilities. Bacterial polysaccharides were more effective than seaweed extracts at low concentrations for friction reduction, but both were much less effective than synthetic polymers. Turbulent-flow frictional measurements were found to be sensitive for the detection, measurement, and partial characterization of long-chain polymers. (Author).
