Thermofluids 3211-2

Course Content
Fluids Links on the web

This is a 3rd year course on fluid dynamics, thermodynamics and energy generation (full title - Thermofluids and Energy Conversion). It is split into two streams : SOE3211 is for students following the 3 year B.Eng course, and SOE3212 for students following the 4 year M.Eng course. 

The course includes two web-based lectures, on dimensional analysis (SOE3211, SOE3212), and on laminar boundary layers (including a discussion on the numerical solution of ode's via the Runge-Kutta method) - this is aimed at the M.Eng students. 

Practical course schedule here, and should be written up in the accepted manner (details here).

Course material and links:

Navier-Stokes equations

Covered in lectures 1, 2, 3 and 4, (notes 1, 2, 3, 4) plus web-based lectures on dimensional analysis (SOE3211, SOE3212), and on laminar boundary layers (including a discussion on the numerical solution of ode's via the Runge-Kutta method) - this is aimed at the M.Eng students. Worksheets 1 and 2 cover this material.

If you want to go considerably deeper into this material, Prof. Cramer has produced a very comprehensive description of the NSE here (but aimed at mathematicians and graduate students as he says).

Basic flows:

Lectures 5 and 6 (notes available: 5, 6) are on aspects including turbulence, turbulent boundary layers and flow around different bluff bodies. 

Turbulence links : turbulence can be investigated in 2d using soap films, or in 3d using a variety of methods (eg. PIV, LIF for a jet). Direct Numerical Simulation (DNS) calculations are also valuable (eg. mixing studies). Turbulence is important in a number of areas such as combustion (also here).

Some links on flow around cylinders: investigated using PIV, and specifically looking at von Karman vortices.

Dimensional analysis is covered in worksheet 3, Boundary layers and external flows in worksheet 4.

Airfoils and Wind Turbines:

Following on from the previous work, lecture 7 covers basic airfoils, and lecture 10 is about horizontal axis wind turbines. (Notes 7, 10).

The starting vortex from an airfoil is demonstrated in this video sequence (RealPlayer version here)

Interesting links on airfoils include the rotorship Bruckau, which demonstrates the basic mechanics of lift generation. Pictures of the human-powered craft Gossamer Albatross, and the solar powered Helios aircraft. Wingtip vortex study using a Boeing 727, and another example of wingtip vortices (business jet). A bullet travelling supersonically, and a jet fighter doing the same thing. The Jfoil programme used in the second assessment is here, and an explanation of the NACA 4 digit scheme is here.

Wind Turbine links - the Danish Wind Industry association has a good web site (not unnaturally, since the wind power industry is most advanced in Denmark) 

Turbomachinery (Turbines and pumps):

Lectures 8 and 9 cover the basics of turbines and pumps (notes 8, 9). Some links to various types of turbine :

Francis (mixed flow) - more info from Wikipedia,
 Kaplan (axial) - more info from Wikipedia, and here.
Miscelaneous - some general pictures, some CFD work (also here). A very comprehensive collection of images is to be found here.
Centrifugal pumps - some background information (for baths and kitchens! but generally applicable) - also a biological example (blood pump), and other examples (1., 2.)

Worksheet 5 is dedicated to turbines.
