The Critical Heat Flux Condition With Water in a Uniformly Heated Microtube
The critical heat flux (CHF) condition needs to be well understood for designing miniature devices involving two-phase flow. Experiments were performed to determine the CHF condition for a single stainless steel tube having an inside diameter of 0.427 mm subjected to uniform heat flux boundary conditions. The effects of mass flux, pressure, and exit quality on the CHF were investigated. The exp...

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...

15 صفحه اولThe Effect of Linear Change of Tube Diameter on Subcooled Flow Boiling and Critical Heat Flux
One of the major industry problems is the flow boiling, where reaching to the critical heat flux (CHF) condition can lead to a temperature jump and damage of the systems. In the present study, the effects of a uniform change in tube diameter on subcooled flow boiling and CHF was numerically investigated. The Euler-Euler model was used to investigate the relationship between the two liquid and v...
