we now have some idea about what models are


We now have some idea about what models are available to simulate the flow over an aerofoil, and

also how to use the Hanley package to apply these methods. Keep referring to your model chart to

remind yourself about the limitations of different models.

 

Go back and reread section 2.5 and figure out the difference between the Navier-Stokes equations

and the Euler equations (i.e. what are the forces that are neglected in the Euler equations).

 

Before the laboratory session do some preparation by reading the following sections in Anderson:

  • Preview box of chapter 4 for motivation
  • Section 4.2 for the language used to describe aerofoils
  • Section 4.3 for characteristics of aerofoils

 

Next week we will look to the assumptions for potential flow in detail. Now we want to start

investigating how aerofoil geometry and the aerodynamic forces and moments are related. This is the

fundamental question a designer asks.  We also need to ask ourselves some questions about the

potential flow option, which is our main tool for the aerodynamic investigation.
