MEG795-001: Numerical Turbulent flow and heat transfer

 

Department of Mechanical Engineering

University of Nevada, Las Vegas

 

Credit hour: three (3)

Fall Semester, 2007

 

Overview:

This is a graduate course that explores the fundamentals of turbulence modeling with computational fluid dynamics (CFD). One of the objectives of this course is to give students an introduction to the numerical methods used to analyze fluid flow and heat transfer. The course is designed to be valuable to both users and developers of CFD codes by providing techniques for interpreting and analyzing the behavior of numerical schemes. The important methods for discretization of the governing equations will be presented, along with the most common algorithms for their solution. Emphasis will be given to finite difference and finite volume methods. Students will be expected to write programs to implement some of the algorithms. The second objective of this course is to present an introduction to fundamental concepts in turbulence flow and heat transfer, and an overview of numerical modeling techniques for the prediction of turbulent flows and heat transfer. The emphasis is on the capabilities and limitations of engineering approaches commonly used in the modeling of turbulent flow and heat transfer.

 

Teaching Goals:

From this course, the students will build necessary background for successful application of CFD for turbulent flow and heat transfer, and be able to solve the turbulent flow and heat transfer problems appearing in the practical applications.
