Turbulence Modeling for CFD (Third Edition)
Publication of the Third Edition ofTurbulence Modeling for CFDhas been motivated by its continuing popularity and Dr. Wilcox's desire to document his recent contributions to the field. It has been adopted for course use in universities all around the world and Dr. Wilcox has presented a short course based on the book many times in the United States and beyond. Demand for the book continues to exceed all expectations.What's New?...All chapters and appendices have undergone improvement and expansion. Most notably, Chapter 4 presents a new version of the k-omega model that includes cross diffusion and a stress limiter. These innovations, inspired by the research of Johan Kok and George Huang, have led to significant improvement of predictive accuracy. The new k-omega model yields close agreement with measurements for boundary layers with pressure gradient, classical free shear flows and separated flows. The improved k-omega model should provide improved predictive accuracy for complex turbulent flows as well as being a source of fresh research ideas.Inclusion of a stress limiter in a unique way yields excellent agreement between computed and measured properties of shock-separated flows from transonic to hypersonic speeds. Recent advances and successes in devising and applying nonlinear stress/strain-rate relations are included in Chapter 6, which also presents a revised stress-transport (second-order closure) model based on the omega equation. The discussion of DNS and LES in Chapter 8 has been expanded and DES has been added. Finally, to enhance the book's utility in the classroom, the number of homework problems has increased by 25%.As with previous editions, the book comes with a companion Compact Disk (CD) that contains source code and documentation for several useful computer programs. In addition to the software provided with the first and second editions, the CD includes a two-dimensional/axisymmetric Navier-Stokes program and some simple grid-generation software. The CD also contains experimental and DNS data in digital form to aid users who wish to compare their own turbulent-flow predictions with measurements.The software on the CD has been modernized and optimized for personal computers running the Microsoft Windows operating system. All programs have menu-driven input-data preparation and plotting utilities, written entirely in Visual C++, that provide a user-friendly environment.
