Drag

Generator Drag Coefficient

Researchers at MIT have demonstrated that wedge-shaped vortex generators attached to a ship's hull can reduce drag by up to 7. 5 percent, which reduces overall ship emissions and fuel expenses. We also establish scaling laws proving that at full-scale drag. . The drag coefficient quantifies the drag or resistance of an object in a fluid environment. Any object moving through a fluid experiences drag - the net force in the direction of flow due to pressure and shear stress forces on the surface of the object. The inline force,, due to a combination of drag and inertia, is expressed by: In this equation: is the volume of the. . In initial flow simulation, Audi a4 car model is imported in CHAM PHOENICS-CFD software and tested under different speeds, then airflow, pressure and velocity value are analysed.
