Atomization mechanisms of a wall-impinging jet in a shallow pool

High-Fidelity Simulations of Primary Breakup and Impinging Jet Atomization

a swot analysis of the english program of a bilingual school in iran

با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...

Numerical simulation of liquid-layer breakup on a moving wall due to an impinging jet

Jet-wiping is a hydrodynamic method for controlling the liquid film thickness in a coating process. In industrial conditions, the jet is generally turbulent. When the jet wipes a liquid film, it usually induces violent film instability called splashing. The instability is characterized by the ejection of droplets from the runback flow. Consequently, it can degrade the final coating quality sinc...

Modeling of Heat Transfer in a Mist/Steam Impinging Jet

The addition of mist to a flow of steam or gas offers enhanced cooling for many applications, including cooling of gas turbine blades. The enhancement mechanisms include effects of mixing of mist with the gas phase and effects of evaporation of the droplets. An impinging mist flow is attractive for study because the impact velocity is relatively high and predictable. Water droplets, less than 1...

Heat Transfer of an Impinging Jet on a Plane Surface

Abstract—A cold, thin film of liquid impinging on an isothermal hot, horizontal surface has been investigated. An approximate solution for the velocity and temperature distributions in the flow along the horizontal surface is developed, which exploits the hydrodynamic similarity solution for thin film flow. The approximate solution may provide a valuable basis for assessing flow and heat transf...
