Simulations in 2D and 3D Applying Unstructured Algorithms

This book was written to students and engineers that like the Computational Fluid Dynamics (CFD) area; in other words, that like of programming algorithms to the resolution of physical problems. Some familiarity with code programming is required. However, through the computation courses teaching at the Universities the engineering student and common areas will have the capacity of programming the codes presented in this book and much more of his/her interest. The applications of this book aim aeronautical and aerospace problems. This book presents the first order unstructured algorithms of Roe (1981), of Steger and Warming (1981), of Van Leer (1982), of Frink, Parikh and Pirzadeh (1991), of Liou and Steffen Jr. (1993) and of Radespiel and Kroll (1995), applied to the class of problems aforementioned. All the algorithms are implemented according to a upwind formulation. Moreover, a second order linear reconstruction procedure is performed with some algorithms that is extended to the others. Good results are obtained with the schemes. A finite volume formulation and unstructured spatial discretization are employed. Turbulence is taken into account by two-equations turbulence models.
