Feeling any pressure lately? Seems the market is slowly bleeding to death on my end.

Practical Method is based on Chen style Tai Chi.

$17 million Zonda Barchetta crashes into Ford Focus.

This update has improved the car performance. The update I'm pointing out is the fillet radius at the bottom of the strakes. This builds up the pressure on the leading face of the strakes, and keeps the high pressure from bleeding into the low pressure side. This increases the vorticity of the flow downstream. Everyone else puts the bottom fillet radius in the direction of airflow.

The Ferrari for instance tried to go with the flow with their strakes.

Now what?

In taoist philosophy, separation of yin yang, that is, separation of opposites generates force. The pressure differential caused by wings, that is the separation of high pressure and low pressure, creates a force. The separation of charge creates an electromotive force. Is it any surprise that Maxwell's equations work so well to describe both electromagnetism and aerodynamics?

Tai Chi, a taoist philosophy derived martial art, says that power is generated when there is yin yang separation.

Which is the better system of rule, better in the sense that everyone benefits. Which is better in the sense of amassing more power? Every Monarchy has fallen, Alexander, Khan, Vlad, Napoleon, Romanov, etc. All by the hands of the occult oligarchy.

The velocity of air through a duct is entirely dependent on the pressure ratio at the throat, and the inlet. Therefore at low vehicle speeds a duct can have 1 bar head, and 1 bar at the outlet. As the vehicle speed increases, the head pressure also increases, meanwhile, the duct pressure decreases at any and all throats, which in turn reduces the pressure at the outlet. The increased head pressure, and reduced outlet pressure together increase the pressure ratio at each throat.

These strakes increase head pressure, as they divert air outward, the inner most strake and the body become the path of least resistance. Now these strakes also restrict air from moving into the back of the floor. Which in effect is lowering the back pressure of the throat created between the inner-most strake and the body. When the pressure ratio reaches ~2:1, you have choked flow. Once you have choked flow, the passage to the back of the floor becomes restricted, which increases the suction behind the strake which pulls the floor downward at that point. However choked flow is very lossy, unless it is carefully controlled. The shape of the outlet has to be carefully designed to exploit the fact that you can accelerate choked flow with careful expansion of the duct.

Not only that, but all subsequent ducts must have this careful sizing in mind, otherwise there are great losses, and flow instability.

You can see in this experiment how critical duct geometry is to maintain low pressure, low loss flow.
