Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes research conducted during the past year whose aim is to develop and test an accurate and efficient method for describing boundary-layer development in the transition region. A low-Reynolds-number version of the Wilcox k-w model has been postulated and tested against experimental data for 10 fully turbulent boundary layers and for more than 20 transitional cases. Overall discrepancies between theory and experiment are smaller than those for simpler correlations designed for use with algebraic turbulence models. Singular perturbation analysis of the compressible viscous sublayer and defect layer has been initiated with some interesting preliminary results. Some progress has been made toward eliminating the k-w model's sensitivity to the freestream boundary condition on w ... Transition, Turbulence modeling, Hypersonics, Computational fluid dynamics.

Download or read book Transition Modeling for Low to High Speed Boundary Layer Flows with CFD Applications written by Ünver Kaynak and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition modeling as applied to CFD methods has followed certain line of evolution starting from simple linear stability methods to almost or fully predictive methods such as LES and DNS. One pragmatic approach among these methods, such as the local correlation-based transition modeling approach, is gaining more popularity due to its straightforward incorporation into RANS solvers. Such models are based on blending the laminar and turbulent regions of the flow field by introducing intermittency equations into the turbulence equations. Menter et al. pioneered this approach by their two-equation γ-Reθ intermittency equation model that was incorporated into the k-ω SST turbulence model that results in a total of four equations. Later, a range of various three-equation models was developed for super-/hypersonic flow applications. However, striking the idea that the Reθ-equation was rather redundant, Menter produced a novel one-equation intermittency transport γ-equation model. In this report, yet another recently introduced transition model called as the Bas-Cakmakcioglu (B-C) algebraic model is elaborated. In this model, an algebraic γ-function, rather than the intermittency transport γ-equation, is incorporated into the one-equation Spalart-Allmaras turbulence model. Using the present B-C model, a number of two-dimensional test cases and three-dimensional test cases were simulated with quite successful results.

Download or read book Turbulence and Transition Modelling written by M. Hallbäck and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to give, within a single volume, an introduction to the fields of turbulence modelling and transition-to-turbulence prediction, and to provide the physical background for today's modelling approaches in these problem areas as well as giving a flavour of advanced use of prediction methods. Turbulence modelling approaches, ranging from single-point models based on the eddy-viscosity concept and the Reynolds stress transport equations (Chapters 3,4,5), to large-eddy simulation (LES) techniques (Ch. 7), are covered. The foundations of hydrodynamical stability and transition are presented (Ch. 2) along with transition prediction methods based on single-point closures (Ch. 6), LES techniques (Ch. 7) and the parabolized stability equations (Ch. 8). The book addresses engineers and researchers, in industry or academia, who are entering into the fields of turbulence or transition modelling research or need to apply turbulence or transition prediction methods in their work.

Download or read book Basics of Aerothermodynamics written by Ernst Heinrich Hirschel and published by Springer. This book was released on 2015-01-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This successful book gives an introduction to the basics of aerothermodynamics, as applied in particular to winged re-entry vehicles and airbreathing hypersonic cruise and acceleration vehicles. The book gives a review of the issues of transport of momentum, energy and mass, real-gas effects as well as inviscid and viscous flow phenomena. In this second, revised edition the chapters with the classical topics of aerothermodynamics more or less were left untouched. The access to some single topics of practical interest was improved. Auxiliary chapters were put into an appendix. The recent successful flights of the X-43A and the X-51A indicate that the dawn of sustained airbreathing hypersonic flight now has arrived. This proves that the original approach of the book to put emphasis on viscous effects and the aerothermodynamics of radiation-cooled vehicle surfaces was timely. This second, revised edition even more accentuates these topics. A new, additional chapter treats examples of viscous thermal surface effects. Partly only very recently obtained experimental and numerical results show the complexity of such phenomena (dependence of boundary-layer stability, skin friction, boundary-layer thicknesses, and separation on the thermal state of the surface) and their importance for airbreathing hypersonic flight vehicles, but also for any other kind of hypersonic vehicle.

Download or read book Intermittency Equation for Transitional Flow written by Ekachai Juntasaro and published by Springer Nature. This book was released on 2022-05-16 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the intermittency equation that is derived a priori. Since the intermittency equation is mathematically obtained, the resulting gamma transition model no longer requires any extra parameters and terms to explicitly account for free-stream turbulence and pressure gradient like the previous transition models. Instead, the present gamma transition model can naturally predict natural transition and effects of free-stream turbulence and pressure gradient on the transition process. Furthermore, the present gamma transition model requires much fewer model constants than the previous transition models. The book is beneficial for CFD researchers in industry and academia who confront modern complex applications involving simultaneously laminar, transitional and turbulent flow regimes, and ideally relevant to graduate students in applied physics, applied mathematics and engineering who are interested in the world of laminar-to-turbulent transition modeling in CFD, or would like to further advance more realistic transition models in the future.
