Spatiotemporal Pinpoint Cooling Sensation Produced by Ultrasound-Driven Mist Vaporization on Skin

Effects of Various Modeling Schemes on Mist Film Cooling Simulation

Numerical simulation is performed in this study to explore filmcooling enhancement by injecting mist into the cooling air with a focus on investigating the effect of various modeling schemes on the simulation results. The effect of turbulence models, dispersed-phase modeling, inclusion of different forces (Saffman, thermophoresis, and Brownian), trajectory tracking, and mist injection scheme is...

Simulation of Mist Film Cooling on Rotating Gas Turbine Blades

Film cooling technique has been successfully applied to gas turbine blades to prevent it from the hot flue gas. However, a continuous demand of increasing the turbine inlet temperature to raise the efficiency of the turbine requires continuous improvement in film cooling effectiveness. The concept of injecting mist (tiny water droplets) into the cooling fluid has been proven under laboratory co...

Sprinkler and mist irrigation for cooling lettuce:effectiveness and economic cosideration

Focal Chorioretinitis Produced by Ultrasound.

Two hundred and forty rabbit eyes toere exposed to focused ultrasonic radiation at either 3.5 me. or 7 me. Circumscribed chorioretinal lesion and localized destruction of the ciliary: body could, be obtained without evidence of injury to other ocular tissues. The sound beam retrodisplaces detached retinas. These observations suggest possible uses of ultrasound in retinal detachment repair, ctjc...

Investigating antimicrobial effect of Zataria extracts produced by ultrasound on salmonella typhimurium

Introduction: Zataria multiflora is a plant of the Lamias family. The most effective antimicrobial composition is its thymol and carvacrol. Salmonella typhimurium is a genus of Salmonella from the Enterobacteriaceae family. This gram-negative basil, optional aerobic or anaerobic, cause diseases such as inflammation of the intestine, systemic infection, and intestinal fever. Th...
