Fuel Economy And Aerodynamics: The Yin And Yang Of Car Design

From the classic Model T to the iconic American muscle cars, the design of cars has been shaped by many factors over the years. Technological advancements, consumer preferences, and government regulations have all played their part. But one factor that has been a game changer is fuel efficiency. The Corporate Average Fuel Economy (CAFE) standards, introduced in the aftermath of the 1973 oil em... » read more

Simulate Rotor Hub Vortex Shedding In Helicopters

Although helicopter aerodynamics involves the same forces that arise in airplane aerodynamics, these forces occur differently due to fluid flow dynamics across the aircraft. Helicopters take advantage of the free stream flow along a rotor blade to produce lift and thrust. In rotating systems, the rotor hub clasps the blades and connects them to the main shaft of the system. The rotor in a h... » read more
