A Numerical Study On The Drag Reduction Of Sedan Car Using Vortex Generator

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.

Analysis of the cause of abnormal noise of Fengjun 5 generator

This sound is usually caused by abnormal friction between the main bearing and the crankshaft journal. The main reason is the excessive clearance between the crankshaft journal and the main bearing, leading to uneven wear and thus producing this abnormal friction and knocking sound. If they are loose, you will hear rattling. Ignoring knocking noises can lead to more significant engine. . When there are abnormal noise in generator set, maybe indicate there are faults in generator set. Worn parts can also generate unusual sounds. These include a high compression ratio, significant thermal load, rough operation, elevated noise levels, and the inability to instantly cut off the fuel. .
