Computational Fluid Dynamics Fundamentals
This course is meant for engineers with little background or experience in engineering analysis using CFD. These could include recently hired engineers, test engineers, or project engineers who want learn what CFD analysis can accomplish.
The goal of the class is to give students a general flavor of what CFD is all about; its advantages, disadvantages, what constitutes a simple vs. a difficult problem, and some questions to ask when reviewing a CFD model and results. Fundamental theories and equations of fluid mechanics will be reviewed. It is not intended to teach the specifics of the numerical algorithms nor how to perform a CFD analysis.
The course will introduce and define the nomenclature used by CFD analysts. Basic concepts such as computational domain, computational grid (mesh), steady or unsteady analysis, compressible or incompressible flow solver, coupled or segregated solver methodology, initial conditions, boundary conditions, physical modeling such as turbulence or cavitation, iterations, residual reduction, and convergence, will be defined.
The course will present material in six main parts. The attendees will first be given a broad introduction to computational fluid dynamics: what it is, what it can and cannot do, and what information is required to perform an analysis and evaluate results. The second section will describe the theoretical background and introduce how CFD theory is used to simulate the behavior of real flow physics. The third part will introduce the definition of computational domain and how to determine computational grids (or meshes), including the selection of different mesh type and sizes.
In part four, descriptions of the fundamental types of numerical algorithms for CFD solvers will be presented, so that attendees will understand the difference between coupled or uncoupled solvers. In part five, an overview of how to incorporate physical modeling into CFD solver will be introduced. This includes the modeling of turbulence, chemical species and reactions, and cavitation. In the last part, an overview will be given of how to examine and quantify CFD results in various contour and line plots, and to assess the potential deviation between CFD and test data.
The course will consist of lecture and discussion only; students will not run any code on a computer.
Seminars begin promptly at 9 a.m. and finish at approximately 5 p.m. each day. Please arrive by 8:45 a.m. The seminar fee includes: course manuals, full color workshop manuals, & instruction. Coffee & donuts in the morning & lunch are provided for each student. Students must make their own travel arrangements. CAE Associates recommends against purchasing non-refundable airline tickets. Please see our course cancellation policy for more details.
