Ultrahigh-speed continuous casting is a critical element in achieving high-efficiency casting. In the present work, three-dimensional model of 160 mm × billet ultrahigh-speed mold was developed for use studying influences different parameters on molten steel flow. The results showed that flow pattern not associated with its speeds, submerged entry nozzle (SEN) immersion depths, or inner diamete...
Laser Doppler anemometry (LDA) and cinematic particle image velocimetry (PIV) measurements of a low Strouhal number oscillatory jet are compared to two-dimensional computational fluid dynamic (CFD) model predictions. The LDA and PIV measurements are recorded from a water model consisting of a jet generated from a submerged entry nozzle (SEN) immersed in a rectangular cavity. The cavity has a wi...
Background and Aim: It is well recognized that implant treatment is common worldwide, but the approach to success is not predictable because of bone loss that occurs around the implants. Also there are many factors affecting crestal bone loss around the implants that one of them is the surgical protocol of implant installation. The purpose of this investigation was to evaluate the amount of cre...
We report on an experimental comparison of the characteristics of quark-induced jets based on an analysis of jet events selected from hadronic events at c.m. energy of 60 GeV in e+e- annihilations. The triangle plot shows that the majority are two-jet events. The three-jet events are also present but not as many as two-jet events. The mean transverse momentum is larger for three-jet events th...
As excess water is discharged from a high dam, low frequency noise (air pulsation lower than 10 Hz, LFN) is generated and propagated in the surrounding areas, causing environmental hazards such as the vibration of windows and doors and the discomfort of local residents. To study the generation mechanisms and key influencing factors of LFN induced by flood discharge and energy dissipation from a...
