A simulation using the navier-stokes differential equations of the aiflow into a duct at 0.003 m/s (laminar flow). The duct has a small obstruction in the centre that is parallel with the duct walls. The observed spike is mainly due to numerical limitations.
This script, which i originally wrote for scilab, but ported to matlab (porting is really really easy, mainly convert comments % -> // and change the fprintf and input statements)
