Each digitized head was then placed in a virtual underwater environment, allowing the researchers to measure water pressure, drag and flow.

“The dimples on a golf ball are an example of separation control that reduces pressure drag by maintaining attached flow around the ball and reducing the size of the wake,” Lang reportedly said on Monday.

There are many forms of drag, but one of the more important kinds in the flight of a ball is known as pressure drag, or form drag.

The Jabulani ball was supposed to remedy some of the unpredictability created by skin friction and pressure drag.

It’s of a lower magnitude than the turbulence created by pressure drag, though.
