Fluid Mechanics 2

Module aims

The ME2 Fluid Mechanics module aims to continue the development of key aspects of engineering fluid mechanics.

Topics include dimensional analysis, the mass-conservation and momentum-balance principles applied to a fluid particle, the differential form of the governing equations (Navier-Stokes), compressible flows (speed of sound, Mach cone, isentropic-flow relations and converging-diverging nozzles). incompressible flows with exact (Couette-Poiseuille flows) and approximate (boundary layers, Blasius solution, lubrication) solutions, and an introduction to turbulence.

ECTS units: 5

Learning outcomes

On completion of this module students should be able to:

1. Select appropriate dimensionless groups and solve scaling problems

2. Select an equation of motion, such as Euler, isentropic flow, Cauchy, Navier-Stokes, as appropriate to solve a problem

3. Simplify and/or approximate the equations of motion to aid solution

4. Apply appropriate boundary conditions and solve the equations

5. Evaluate the forces exerted by a fluid on its boundaries

Module syllabus

Dimensional analysis. Notion of a fluid particle (continuum model assumption). Kinematics of a fluid particle. The material derivative. The Navier-Stokes equations. Exact solutions (laminar Couette-Poiseuille flows). Approximate solutions (boundary layers, Blasius solution, lubrication). Introduction to turbulence (origin, time-averaged governing equations, eddy viscosity) with application to channel/pipe flows. Compressible flows: speed of sound, Mach cone, isentropic-flow relations, converging-diverging nozzles.
