100 Year-Old Aerodynamics Problem Solved: Could Increase MPG Dramatically

100 Year-Old Aerodynamics Problem Solved: Could Increase MPG Dramatically - The Green Optimistic

MIT researchers discovered the solution to a problem put 100 years ago by Ludwig Prandtl. It refers to the situation when, for example, a car accelerates up and down a hill, then slows to follow a turn, and the airflow around it cannot keep up and separates from it. This aerodynamic phenomena creates an additional drag, slowing the car, and forcing you to push harder on the pedal, consuming more gas. The same applies to airplanes, boats, subs, and generally, any moving object following the rule mentioned above.
