Heat dissipation per unit volume has grown rapidly, as the size of modern electronic devices has continued to decrease. The air flow induced by an oscillating cantilever blade enhances the heat transfer performance of high heat density devices. The heat transfer improvement mainly depends on the velocity magnitude and distribution of air streams induced by the vibrating blade. Accordingly, this...

Blade imperfections are a significant explanation behind low quality and of shame for makers. Review forms done on these commercial ventures are for the most part manual and tedious. To diminish mistake on recognizing sharpened steel deformities requires more auto and precise review process. Considering this failing to offer, this examination actualizes a Blade Defect Recognizer which utilizes ...

Aiming at the non-stationary and stall flutter problems of wind turbine blade caused by transient load fluctuations, the dynamic properties of wind turbine were studied, the blade was simplify to a cantilever beam in case of the action of shear deformation and cross section rotating effect were considered in this analysis, equations of the blade were established based on D'Alemberts' principle ...

In the paper production, doctor (scraping) blades are placed in contact with press rolls during wet pressing so as to purge the surface of the rolls from processing water, contamination, and stickies. The contact is achieved by mounting the blade on a holder, which is tilted around a rotation axis until the blade tip contacts with the roll. The contact force is determined by the supply pressure...

A mathematical model for enhancing the torsional stability of a slender, tapered, composite wind turbine blade is presented. The increase of the stability boundary is measured by maximization of the critical wind speed at which failure may occur by aeroelastic divergence in parked-turbine state. The total structural mass of the blade is kept constant in order not to violate other economic and p...

The objective of this research is to develop a turbine blade investment casting cost advisor model to assist a blade designer in decision-making in a concurrent engineering environment. It is a microcomputer based cost estimating system that employs a manufacturing knowledge base. The concept of the manufacturing process for blade production by the investment casting method is used to develop t...

the machine to be designed and developed with a view to resolve one ofthe irksome problems of this institute has been facing every year. this institute issurrounded by vast non- fertile land area of about 200 acres, which becomes widelyoccupied by numerous breads of bushes and shrubs during post-rainy season. due tothis unwanted proliferation of such verdant institute gets abysmal look and that...

The material properties of food can exert a significant influence on tooth morphology. Although the stiffness or toughness of a material is usually of prime concern, other aspects of material properties (such as extensibility) can be of equal importance. Previous experimental work on the effect blade shape has on fracturing biological materials indicated a notched blade greatly reduced the work...

This study investigated the mechanical properties of a new rectangular compaction blade and compared this blade with other types of nail. Three types of nail were tested: the Magnum lag screw (Robert Reid Inc, Tokyo, Japan), proximal femoral nail, and Magnum Fid blade (Robert Reid Inc). The nails were inserted into solid rigid polyurethane foam, and the torsional moments were loaded with an Ins...
