Below, the first two years of my phd in 4 videos. Colorful Fluid Dynamics I call them. They don’t mean anything other than being fency.

Two counter rotating wind turbine rotors with Actuator Line method. There are oscillations in the flow due to the high order finite difference scheme on the vertical axis. I replaced that scheme with a second order afterwards. On ground parallel, it has spectral fourier schemes.

 

In boundary layer simulations, its not easy to find a turbulent box that is large enough and long enough to be fed to do a developed flow simulation for wind turbines. Below there are two simulations running and only one of them has the pressure gradient inside. The other, only being driven by the first simulation’s output by adding controlled body forces to the momentum equations directly. 

 

A dummy developed channel flow LES with wall and simple Smagorinsky models. u and w velocities respectively.

With the injection fuel systems you have so called throttle bodies. Its the valve you see thats popping out of the hood of these muscle cars. It opens and closes with the throttle and adjusts the incoming air flow. This airflow generates a pressure drop and this negative pressure directly affects the amount of the fuel that gets injected before the air-fuel mixture reaches to the piston. If you have your throttle bodies misalligned, you get this pressure imbalance in pistons and you feel a bit more vibration during idling. There are pressure gauges that you can connect to the throttle body and make the necessary adjustments accordingly. Below in the video you will see a home made one that uses water, aquarium hose and couple of stylograph ink drops for some visibility
