An Experimental Study of Nanofluids Operated Shell and Tube Heat Exchanger with Air Bubble Injection
Shell and Tube heat exchangers are the heat exchangers that are most widely used in industries and for other commercial purposes. There are many techniques that have been utilized to enhance the heat transfer performance of the shell and tube heat exchangers. Air bubble injection is one of the promising and inexpensive techniques that can create turbulence in the fluids resulting in to enhancem...
متن کاملNumerical Study Scour Pattern on Channel Bend Using Flow-3D Software
In nature, a direct route to the river is uncommon. Most rivers have channels that bend wherea complex scour pattern dominates. We have intended to study the behavior patterns necessary to scour a river known as the dominant bends. Numerical models are powerful instruments for the prediction of such areas and can provide a good understanding of these areas. In the present study we have used a t...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولFlow Boiling on Micropin Fins Entrenched Inside a Microchannel—Flow Patterns and Bubble Departure Diameter and Bubble Frequency
Flow boiling of HFE 7000 in five parallel microchannels of 222 m hydraulic diameter, each containing a single row of 24 in-line 100 m pin fins, was investigated. High speed photography revealed the dominant flow patterns, namely, the bubbly flow, the multiple flow, and the wavy-annular flow. The interaction of the bubble with the pin fins during nucleate boiling from G 350 kg /m2 s to G 827 kg ...
