Book excerpt: The asymptotic boundary layer problem involving an axial incompressible Newtonian fluid flow past a circular cylinder parallel to its axis was investigated by Stewartson (1955). He addressed hiself primarily to the Mangler's (1948) derivation, namely, the character of the boundary layer on a circular cylinder is equivalent to that on a flat plate owing to the boundary layer thickness being small compared with the radius of the body. Stewartson found from his investigation that if the velocity of the main stream is constant, the skin friction on the cylinder is increased at the corresponding points of a flat plate due to the effect of the transverse curvature of the cylinder, and, for the same reason, that the boundary layer thickness is slightly reduced in comparison with that of the flat plate. Thus, there certainly exist differences between the behavior of boundary layer on a circular cylinder and that on a flat plate. In this thesis we investigate the behavior of the asymptotic boundary layer of an axial incompressible micropolar fluid flow on a circular cylinder, and obtain the boundary layer solutions and their characteristics arising out of the orientable nature of the fluid medium. The present investigation is found to lead to the confirmation of the longstanding famous conjecture of Eringen (1966) that the theory of micropolar fluids may have a mechanism capable of explaining drag reduction near a solid boundary. Expressions for the velocity and microrotation fields in the boundary layer as well as those of skin-friction and boundary layer thickness are obtained. This thesis also presents a review of several existing continuum and microcontinuum constitutive theories of great interest to orientate the recent trend in the field of continuum mechanics and to provide for ready reference.

Book Synopsis Integral Methods in the Theory of the Boundary Layer by : Lev Gerasimovich Loĭt͡si͡anskiĭ
Download or read book Integral Methods in the Theory of the Boundary Layer written by Lev Gerasimovich Loĭt͡si͡anskiĭ and published by . This book was released on 1944 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of the well-known basic principle of mechanics, the principle of Jourdain, to problems of the theory of the boundary layer leads to an equation from which the equations of Von Karman, Leibenson, and Golubev are derived as special cases. The given equation may be employed in other integral methods. The present paper deals with the method of the variation of the thickness of the boundary layer. A number of new approximate formulas valuable in aerodynamic calculations for the fristion distribution are derived from this procedure. The method has been applied only to laminar boundary layers, but it seems probable that it may be generalized to include turbulent layers as well.

This book was released on 2012-12-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern with the class of problems investigated in this monograph began for me as a graduate student at MIT (1958-62) when serving as research assistant to Professor Eric Reissner who initiated me into the subject and whose influence - whether directly or dialectically - is probably discernable in the contours of the work. My fIrst attempt at a systematic derivation of the equations of shell theory was made while on a summer assistantship with Professor Norman Levinson in 1960. Beyond gaining a sobering reali zation of the complexities involved, I made little progress at that time. In 1962-64 while a Temporary Member at the Courant Institute of Mathematical Sciences (NYU) I made a fresh start, while benefIting from my association and discus sions with Professor Fritz John. With the conviction that the full integration of the equations with respect to the thickness coordinate, by means of the Legendre repre sentations, must lead to a clarifIcation of the position of the two-dimensional theory in its three-dimensional context, the necessary computations were completed during that period. Several years passed while I became reconciled with the thought that the material needed to be organized as a monograph. This was done during 1969-70 while at the NASA Electronics Research Center in Cambridge, MA.

This book was released on 1978 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two similarity laws for a thick, axisymmetric, turbulent boundary layer on a long circular cylinder have been established. The validity of the assumption of constant-stress moment in the law-of-the-wall region is analyzed under the assumption of similarity. A new logarithmic mixing length, which takes into consideration the effect of transverse curvature on turbulence, is proposed for the law-of-the-wall region. With this logarithmic mixing-length models, the mean-flow momentum equation yields a law-of-the-wall relation in terms of the exponential integral in the logarithmic portion of the inner layer. Comparisons with available data and other proposed relations reveal that this logarithmic law gives a definite improvement. Also a mathematical explanation is given as to why the cylinder data do not deviate appreciably from the classical two-dimensional law-of-the-wall, even though it is observed that the turbulent characteristics, such as the size of large eddies and the turbulent intensities are much smaller than for a flat plate.
Book Synopsis Boundary Layer Flows: A Mathematical Approach by : Aron Jimenez
Download or read book Boundary Layer Flows: A Mathematical Approach written by Aron Jimenez and published by States Academic Press. This book was released on 2021-11-16 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The layer of fluid wherein the effects of viscosity are significant and which exists in the immediate vicinity of a bounding surface is known as a boundary layer. Boundary layer equations such as Bernoulli's equation, Prandtl's transposition theorem, energy integral, Von Mises transformation, and Crocco's transformation equations are necessary for the understanding of boundary layer flows. They are also a vital point of fluid dynamics. In mathematical analysis of fluid dynamics, one of the central problems is the asymptotic limit of the fluid flow as viscosity becomes zero. This book unravels the recent studies in the field of boundary layer flows. It will also provide interesting topics for research which interested readers can take up. This book is a vital tool for all researching or studying about boundary layer flows as it gives incredible insights into emerging trends and concepts.

Download or read book Secondary Instabilities of Görtler Vortices in High-Speed Boundary Layers written by Jie Ren and published by Springer. This book was released on 2017-10-27 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis first reveals the mechanism of Görtler instabilities and then demonstrates how transitions at hypersonic flows can be effectively controlled (either promoted or suppressed) with Görtler or Klebanoff modes. It focuses on understanding and controlling flow transitions from mild laminar to fully turbulent flows at high speeds—aspects that have become crucial at the dawn of an incredible era, in which hypersonic vehicles are becoming available. Once this occurs, it will be possible to travel from Beijing to Los Angeles within just 2 hours, and we will all live in a genuinely global village—and not just virtually, but physically. Görtler instabilities have often been used to promote flow transition in hypersonic vehicles. However, how Görtler instabilities are excited and how they evolve in hypersonic flows are questions that have yet to be answered.
