CATALOG DATA:
A graduate level course designed to introduce students to experimental methods used in ?uid dynamics research. It includes both a theory of instruments and sensors component and a laboratory component. The lab component is designed to demonstrate the use of different sensors as applied to different ?ow situations that are classic in the literature.

TEXTBOOK:
none.

GOALS:
The object of this course is to teach the students about the different types of sensors, instrumentation and time-series analysis that are used in conducting experiments in ?uid dynamics research. An emphasis is placed on the systems response of di?erent sensors as a means of determining the most applicable measurement approach for a particular application.
