A measuring method to detect wall flow topologies by active infrared thermography was developed.Quadcopter rotor blades were studied in typical hover and forward flight conditions, while using a high-power infrared laser to heat the blade surface.By this, the distance Envelope between heat source and measuring object could be significantly increase
Oral pyogenic granuloma is an inflammatory hyperplasia seen in the oral cavity occurring in response to stimuli such Face Mist as local irritants and hormonal factors.Port-wine stain is a congenital capillary malformation which manifests on the mucosa or skin.Pyogenic granulomas in the oral cavity have rarely been reported to be present in congenit
In this study, a jet injection propeller was designed to increase its efficiency, and the results were compared by open water tests and numerical computations.Also, the change in shape of the slit and injection volume conditions, which are difficult to perform experiments with, were analyzed through computations.The jet injected from the blade surf
