High-Pressure Turbine Aerodynamic Enhancement Using Rotor Tip Desensitization Technique
EnergiesTurbines experience pressure losses from various sources, one of which is the tip leakage flow in the rotor blades. This is one of the main factors responsible for the decrease in turbine efficiency. This leakage is caused by pressure differences between

Computational Fluid Dynamic Analysis to determine Downforce of Motorcycle Winglet [PDF]
, 2020 Competitive motorcycling is all about being fast. However, frontal lift (i.e. ‘wheelie’) has high tendency to occur at high speed of travelling. Frontal lift is when the front wheel is no longer in contact with the ground, thus, results in the loss of ...
