09458 - Fluid Dynamics

Course Unit Page

Academic Year 2018/2019

Learning outcomes

The course offers a quantitative description of the equations that govern fluid motion. At the end of the lectures the student is able to understand the basic phenomenology of fluid dynamics and use the learned models to solve problems relevant to Aerospace Engineering.

Course contents

Introduction to fluid properties. Pressure, viscosity, surface tension and capillarity. Non-Newtonian behaviour. Statics of fluids. Dimensional analisis. Introduction to tensorial analysis. Eulerian/Lagragian description. Reynolds transport theorem. Conservation of Mass. Conservation of Momentum. Conservation of Energy. Constitutive relations for Newtonian and non Newtonian fluids. Entropy balance. System of equations for fluid mechanics. Non dimensional parameters. Finite difference methods for convection-diffusion. Natural and forced convection. Low Reynolds number flows, Stokes flow. High Reynolds number flows. Euler equations. Irrotational flows: vorticity and circulation.  Introduction to potential flows and boundary layer.
