Laminar-Turbulent Transition

AAE62400

Credit Hours: 3

Learning Objective:
**IMPORTANT COURSE DETAILS** The majority of the course content will be delivered via synchronous (real-time) telecon format. Slides available in advance on the web in PDF form and shown to students using Adobe Connect. Please contact the instructor for details.

Description:
Instability mechanisms, such as: Kelvin-Helmholtz, Tollmien-Schlichting, Gortler, and crossflow. Secondary instabilities. Nonlinear and nonparallel effects. The Parabolized Stability Equations. Receptivity. Transition prediction. Effects of compressibility, heating, roughness, turbulence, noise, curvature, etc. Turbulent spots and the extent of transitional flow. F2016 Syllabus

Topics Covered:
Introduction: Mechanisms of transition: linear and nonlinear instability, secondary instability, environmental noise, bypasses. Limitations of algebraic correlation schemes. Review of elementary wave theory. Review of the basic concepts of random processes and spectral analysis ;Linear Instabilities; General Parametric Effects; Supersonic and Hypersonic Effects; Advanced Methods for Analysis and 'Prediction' - a) transient growth, b) nonlinear and secondary instabilities, c) beyond local methods; Intermittency and the Extent of Transition; Roughness Effects; Case Studies; Receptivity.

Prerequisites:
AAE511 or equivalent. Consent of instructor (steves@purdue.edu) required to register - send approval email to ProEd (proed@purdue.edu) for a registration override. This is a synchronous course; students will need to refer to slides posted on a website and teleconference on MWF for 50 minute 'live' lectures.
