Download or read book Numerical Model For Fluid Spin Up in A Partially Filled Cylinder written by Gregory F. Homicz and published by . This book was released on 1982 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical investigation is presented for the axisymmetric spin-up of fluid in a partially-filled cylindrical cavity. It is an extension of the earlier analyses of Wedemeyer, and of Goller and Ranov, to those cases where the liquid free surface intersects one or both endwalls. The simplifying assumptions of a columnar flow and the quasi-steady treatment of the Ekman layer pumping of the secondary flow are retained. Earlier estimates of the Ekman layer pumping are modified heuristically for situations where the layer(s) no longer covers the entire wall. Also, due to the very steep free surface contour in the latter stages of spin-up, it was found advantageous to develop the free surface equations in an axial, rather than radical, coordinate frame.

Available in PDF, EPUB and Kindle. Book excerpt: This is the final report describing a three year theoretical investigation of the dynamics of fluid spin-up in a partially-filled cylindrical cavity. The effort was divided into two phases. The first phase consisted of developing an extension of the earlier analyses of Wedemeyer, and of Goller and Ranov, to those cases where the liquid free surface intersects one or both endwalls. The simplifying assumptions of a columnar flow and the quasi-steady treatment of the Ekman layer pumping of the secondary flow are retained. Earlier estimates of the Ekman layer pumping are modified heuristically for situations where the layer(s) no longer covers the entire wall. Also, due to the very steep free surface contour in the latter stages of spin-up, it was found to advantageous to develop the free surface equations in an axial, rather than radial, coordinate frame. This model and the resulting computer code are the subject of an earlier interim report and a subsequent paper submitted for journal publication. Accordingly, only a summary of this phase and its results is presented here. No experimental or numerical data were available against which to compare the simplified model's predictions for cases where the free surface intersects one or both endwalls. Accordingly, in the second phase of the program a more refined numerical model was developed, based on the full nonlinear Navier-Stokes equations. This is a finite difference code in which the primitive variable equations are solved in conservative form. The development of the governing equations, and the semi-implicit predictor-corrector scheme used to solve them, are presented in some detail.

This book was released on 1990 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: space commercialization activities are mainly in the areas of telecommunication and Earth observation. The commercial use of space for microgravity processing remains elusive. The reasons for this are the knowledge base for microgravity processing is inadequate and flight opportunities and hardware are too expensive, lengthy, and risky to provide a reasonable return on investment. Furthermore, previous unrealistic predictions of large benefits from space manufacturing of crystals, biomaterials, and other materials have created a negative image of microgravity opportunities, especially in connection with the justification of manned space flights and the construction of a large space infrastructure. This volume reports on the progress in Space Commercialization activities.

Available in PDF, EPUB and Kindle. Book excerpt: The problem of liquid sloshing in moving or stationary containers remains of great concern to aerospace, civil, and nuclear engineers; physicists; designers of road tankers and ship tankers; and mathematicians. Beginning with the fundamentals of liquid sloshing theory, this book takes the reader systematically from basic theory to advanced analytical and experimental results in a self-contained and coherent format. The book is divided into four sections. Part I deals with the theory of linear liquid sloshing dynamics; Part II addresses the nonlinear theory of liquid sloshing dynamics, Faraday waves, and sloshing impacts; Part III presents the problem of linear and nonlinear interaction of liquid sloshing dynamics with elastic containers and supported structures; and Part IV considers the fluid dynamics in spinning containers and microgravity sloshing. This book will be invaluable to researchers and graduate students in mechanical and aeronautical engineering, designers of liquid containers, and applied mathematicians.
