Numerical study of surface tension effects on bubble detachment in a submerged needle
This paper analyses adiabatic gas bubble formation, growth, and detachment which are produced from a submerged needle in water with the aim of elucidating the impact of surface tension on bubble properties. A simulation model is utilized to enable examination of the problem for the mentioned parameter. The numerical results are compared with experimental observations on the bubble for validatio...
متن کاملNumerical simulation of bubble interactions
Introduction Single bubble dynamics has been intensively investigated theoretically, experimentally and numerically during the last century [1]. Analysis of the interactions between bubbles in a cavitating flow or the interactions among an individual bubble pair has risen from the demand of a more comprehensive understanding of bubble dynamics. When a bubble is induced near an interface by a la...
متن کاملExperimental investigation of bubble growth and detachment in stagnant liquid column using image – based analysis
An experimental study has been carried out to characterize bubble formation, growth, and detachment mechanisms in a stagnant liquid column. Both bubble frequency and bubble detachment size were measured in different gas flow rates, injector diameters and orientations, submergence height, and liquid properties. Experiments were performed for air injection flow rate ranges between 200 mlph and 12...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
