In my uni years I went to a lot of science conferences; one of the papers that I remember very was about ships propellers and how it can create thrust. A comparison was made with lift on an aerofoil. As the author put it, the lift appears as a pressure difference on the tow faces of the aerofoil. The difference appears because the velocity of air on the upper is larger than that on the lower face....

Open source solutions for computer aided simulations
Introduction
Any engineering problem
can be solved with one of the following approaches: analytical, experimental
and numerical; from these, numerical analysis is the single most effective tool
that can give insight to virtually any level of detail. Numerical analysis is
practically a science placed...

2D Transport of a Passive Scalar with OpenFOAM
All the posts that have been written until now tackled the shockTube problem and the 1D transport problem; we've seen the convection and diffusion at work and we saw that there are a lot different schemes for divergences modelling.
In the following I will show the setup and results for 2D scalar transport...
