MATLAB Lift calculator.

[n72.75]

A friend of mine is working on a MATLAB project involving lift calculations based on a user-defined airfoil shape.

What I was wondering was if any of the community members where well versed in computational fluid dynamics and any of the mathematics behind it.

The answer is yes. Any specific question?

Matthew: Very interesting. I assume he's using a panel methods approach?

I'm trying to help him but I lack the knowledge of the mathematics.

He was at first, but he's trying to move to a more general case, involving thick airfoils

My thoughts are to use a curve integral to integrate differential pressure across differential area.

What we need to figure out is how to find the pressure at any point surrounding the airfoil, is it possible to accomplish this with a massive amount of fluid vectors each assigned a mass? If so, how do we account for compressibility.

One goal is that the simulation be general enough that so the simulation need not be specific to hypersonic, or subsonic speeds.

Computation power is not an issue.
