92-590-31 Unsteady Aerodynamics and Noise Generation Modeling

Semester: Fall 2005

Instructor: Dr. G.W. Rankin, Mechanical, Automotive and Materials Engineering

Restrictions: Students will not be allowed to register over the web. They must get

signed in using add/drop forms with the permission of the instructor.

Course Description:

In this course practical methods of modeling the generation of aerodynamic noise (aeroacoustics)

will be studied. The methods to be considered include direct numerical simulation,

integral methods based on the acoustic analogy and various broadband-noise-source-model

methods. Emphasis will be placed on understanding the fundamental aspects of the methods and

their relationship to fluid mechanics as well as the steps necessary for implementation in

computational fluid dynamic codes. In addition, certain aspects of the generation of noise

caused by vibrating surfaces (vibro-acoustics) will be considered. This section will focus on the

concept of the apparent mass of a vibrating object.

Method of Instruction:

The instruction will, primarily, be of a directed special study format with selected readings from

classical papers and chapters of certain textbooks on the topics assigned. In addition, however, it

is planned to invite a number (3 to 5) experts in the field to give guest lectures on topics of their

expertise. In order to make this feasible, from a financial perspective, the use of video

conferencing and distance learning techniques will be investigated.

Method of Evaluation:
