The objective of this course is to familiarize the student with the experimental techniques associated with current research in aeroacoustics.Thus, methods associated with characterizing the mean and fluctuating properties of gas flows in addition to techniques associated with noise measurement will be presented.

 

Experimental design, uncertainty analysis, pressure probes, temperature probes, anemometry, optical techniques (Schlieren, Doppler velocimetry, Particle Image Velocimetry), acoustic measurement, surface pressure measurement.

Because no single source exists that covers all of the intended lecture topics, the lectures will consist of material excerpted from numerous reference texts, journal articles, and manufacturers? literature.  Handouts will be provided, as appropriate, and reference books will be kept on reserve in the University Library.  It is the student?s responsibility to review material highlighted in the lectures.

 

A minimum of three laboratory experiments will be conducted.  They will involve pressure, velocity and acoustic measurements around a jet.  The assignment will involve taking measurements, as part of an in-class work exercise, and then preparing a report and analyzing the data.

The midterm examination will consist of a take home assignment and will be given in the middle of the course.  The assignment will cover material from the first half of the course.

 

As a group project, students shall be expected to design and conduct an experiment during the last two weeks of the course The students shall be expected to prepare an individual written report present their results explaining the experiment.

Students are expected to follow the honor code as outlined in the current University of Mississippi M Book.  Although it is permissible for students to work together on homework problems as such collaboration facilitates learning, direct copying of others? work without a legitimate collaboration of effort constitutes a violation of the honor code.  No collaboration will be tolerated on examinations.
