This book was released on 2018-07-17 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes two approaches to low Reynolds-number k-epsilon turbulence modeling which formulate the eddy viscosity on the wall-normal component of turbulence and a length scale. The wall-normal component of turbulence is computed via integration of the energy spectrum based on the local dissipation rate and is bounded by the isotropic condition. The models account for the anisotropy of the dissipation and the reduced mixing length due to the high strain rates present in the near-wall region. The turbulent kinetic energy and its dissipation rate were computed from the k and epsilon transport equations of Durbin. The models were tested for a wide range of turbulent flows and proved to be superior to other k-epsilon models, especially for nonequilibrium anisotropic flows. For the prediction of airfoil heat transfer, the models included a set of empirical correlations for predicting laminar-turbulent transition and laminar heat transfer augmentation due to the presence of freestream turbulence. The predictions of surface heat transfer were generally satisfactory. Kwon, Okey and Ames, Forrest E.

Download or read book Applied Computational Fluid Dynamics and Turbulence Modeling written by Sal Rodriguez and published by Springer Nature. This book was released on 2019-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique text provides engineering students and practicing professionals with a comprehensive set of practical, hands-on guidelines and dozens of step-by-step examples for performing state-of-the-art, reliable computational fluid dynamics (CFD) and turbulence modeling. Key CFD and turbulence programs are included as well. The text first reviews basic CFD theory, and then details advanced applied theories for estimating turbulence, including new algorithms created by the author. The book gives practical advice on selecting appropriate turbulence models and presents best CFD practices for modeling and generating reliable simulations. The author gathered and developed the book’s hundreds of tips, tricks, and examples over three decades of research and development at three national laboratories and at the University of New Mexico—many in print for the first time in this book. The book also places a strong emphasis on recent CFD and turbulence advancements found in the literature over the past five to 10 years. Readers can apply the author’s advice and insights whether using commercial or national laboratory software such as ANSYS Fluent, STAR-CCM, COMSOL, Flownex, SimScale, OpenFOAM, Fuego, KIVA, BIGHORN, or their own computational tools. Applied Computational Fluid Dynamics and Turbulence Modeling is a practical, complementary companion for academic CFD textbooks and senior project courses in mechanical, civil, chemical, and nuclear engineering; senior undergraduate and graduate CFD and turbulence modeling courses; and for professionals developing commercial and research applications.

This book was released on 2016-11-03 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Essay from the year 2016 in the subject Engineering - Mechanical Engineering, grade: A, KTH Royal Institute of Technology (School of Engineering Sciences), course: Applied Computational Fluid Dynamics, language: English, abstract: Concentrating Solar Power Receiver (CSPs) collect solar radiation with large mirrors and reflect them concentrated on a receiver. Here, a Dish-Stirling type thermal cycle is driven. One of the key preconditions for a cost competitive production of power is a good efficiency factor. Within the framework of this project, we want to examine and qualitatively quantify the heat losses of a Dish Sterling Concentrating Solar Power Receiver. It is the aim to determine the individual driving forces for heat losses by analysing natural convection on the one hand and two different setups of forced convection on the other hand. In section 2, we present the abstract model of a solar receiver. Then, we will discuss the necessary models to simulate turbulent flow and heat transfer of air and justify our choice of numerical methods to solve the governing equations in ANSYS Fluent. Furthermore, we will introduce performance factors to monitor the heat losses of the solar receiver. Coherent with the two main physical phenomena of heat losses, we subdivided the report in normal convection (NC, section 3) and forced convection (FC, section 4), where we outline the specific model characteristics, boundary conditions, grid requirements and benchmarks respectively. A profound analysis of the results and an outlook on further research in section 5 finalise the report.

Available in PDF, EPUB and Kindle. Book excerpt: Turbulence is one of the key issues in tackling engineering flow problems. As powerful computers and accurate numerical methods are now available for solving the flow equations, and since engineering applications nearly always involve turbulence effects, the reliability of CFD analysis depends increasingly on the performance of the turbulence models. This series of symposia provides a forum for presenting and discussing new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. The papers in this set of proceedings were presented at the 5th International Symposium on Engineering Turbulence Modelling and Measurements in September 2002. They look at a variety of areas, including: Turbulence modelling; Direct and large-eddy simulations; Applications of turbulence models; Experimental studies; Transition; Turbulence control; Aerodynamic flow; Aero-acoustics; Turbomachinery flows; Heat transfer; Combustion systems; Two-phase flows. These papers are preceded by a section containing 6 invited papers covering various aspects of turbulence modelling and simulation as well as their practical application, combustion modelling and particle-image velocimetry.
