SESS2022 Hydrodynamics

Module Overview

In this module the fundamental concepts of hydrodynamics are introduced. The main focus is on inviscid, incompressible flow, but viscous effects including boundary layers and separated flow are introduced as well. The lectures are complemented by laboratory sessions with relevance to the taught material.

Syllabus

Introduction: Fundamental concepts: Velocity field, streamlines & streamfunctions, Euler's & Bernoulli's equations, vorticity & irrotational flow, velocity potential, role of Laplace equation. Flow elements and superposition: Uniform stream, source/sink, line vortex, uniform flow with source, Rankine oval, flow around circular cylinder/doublet, circulation, lifting flow over circular cylinder and Kutta-Joukowski theorem, Kutta condition, method of images. Thin Foil Theory: Vortex sheets, flat plate lifting surface (lift-versus-angle of attack & centre of pressure), camber & surface pressure distribution. Finite Lifting Surfaces: Downwash & induced drag, Biot-Savart law, bound vorticity, horseshoe vortex, classical lifting line theory, application to elliptic & general planforms. Viscous flow: Flow regimes, boundary layers, integral properties of boundary layers (displacement thickness, momentum thickness & shape factor), momentum integral equation for a flat plate, power law approximations for turbulent boundary layers, drag on a flat plate for laminar and turbulent flow including transition, separation and pressure drag Laboratory sessions: 1) Boundary layer lab – measuring velocity profiles of laminar and turbulent boundary layers 2) CFD lab – application of commercial CFD software to flow over an aerofoil 3) Wind tunnel lab for an infinite foil – measuring pressure distribution and integrating it to estimate lift. 4) Wind tunnel lab for a finite rudder/hydrofoil - measuring lift and drag of a finite wing and assessing its performance
