    Course Overview

    Introduction to Shock-Wave/Boundary-Layer Interactions

    Synopsis

    This course introduces the basics of shock-wave/boundary-layer interactions (SBLIs). It begins a very brief revision of fundamental fluid mechanics, in particular gasdynamics and boundary layers. This is followed by an explanation of the different types of SBLIs before describing in more detail the fundamental flow physics of a number of nominally 2-dimensional interactions. The difference between attached and separated interactions is discussed and some basic criteria for the prediction of the separation onset are described.

    In the second part of the course 3-dimensional interactions are introduced in greater detail, concentrating on flow topology and key physics (inc. unsteadiness). This is followed by an overview of flow control techniques, distinguishing between boundary-layer and shock control methods and explaining the relative objectives and merits of each approach. Finally, recent research into the influence of corner flows on nominally 2-dimensional interactions is described.

    Key Topics 

    • Revision of relevant fluid mechanics knowledge
    • Understanding of the different scenarios where SBLIs occur
    • Detailed knowledge of fundamental 2- and 3-dimensional SBLIs, including flowfield topology, flow variables, separation and unsteadiness
    • An understanding of current state-of-the-art of flow control relevant to SBLI (function, efficacy and potential)
    • An understanding of more complex 3-dimensional effects

    Who Should Attend

    For professionals (and students) new to, or wishing to move into, applications/research areas affected by SBLIs and who need a thorough introduction. Also useful for individuals somewhat familiar with the basics but need to deepen their understanding. Undergraduate-level knowledge of fluid mechanics (incompressible flow, viscous flow, basic gasdynamics) is expected.
