The cooling of the tip surface of a turbine blade is a critical issue with respect to the increase in turbine inlet temperatures.
These vortex generators were placed over low-pressure surface of blade or tip blade part.
The design process corresponds to the classical construction of a blade using the medial surface of the blade and profile curves attached to it.
The propeller is driven by the water current and on the surface of the blade the pressure decreases and an air sucking effect takes place.
Video laryngoscopy (VL) was developed to obviate the need for direct visualization of the glottic inlet by transporting the view of the airway to a monitor via a micro video camera placed on the under surface of the blade.
Using three-dimensional computer graphics, a Bezier surface of the rear surface of the blade was generated.
Each vein marks the position of a vascular bundle, and the tissue over the bundle is raised producing a ridge so that the adaxial surface of the blade is corrugated.
It is not only essential to squirt oil into the bearings and axle on which this spins, it is also a good idea to smear a light coat of waterproof grease over the surface of each blade or impeller in order to keep snow from sticking to it.
The surface of the blade is covered with deep scratches along its length, a result of intensive cleaning from rust before every coronation, probably with sand or brick powder.
Pressure acting on the surface of rotor blade is measured during rotation by multiport pressure devices and transmitted to a stationary system through wireless LAN.
