[ 1 ] - Flow Pattern and Oil Holdup Prediction in Vertical Oil–Water Two–Phase Flow Using Pressure Fluctuation Signal
In this work, the feasibility of flow pattern and oil hold up the prediction for vertical upward oil–water two–phase flow using pressure fluctuation signals was experimentally investigated. Water and diesel fuel were selected as immiscible liquids. Oil hold up was measured by Quick Closing Valve (QCV) technique, and five flow patterns were identified using high-speed photo...
[ 2 ] - Microbial Enhanced Oil Recovery, Wettability Alteration and Interfacial Tension Reduction by an Efficient Bacterial Consortium, ERCPPI-2
In the present study, the potential of a bacterial consortium of Enterobacter cloacae and Pseudomonas sp. (ERCPPI-2) for microbial enhanced oil recovery was investigated. Various mechanisms of enhanced oil recovery (EOR) as a result of using ERCPPI-2 and its metabolic products were studied in detail. The obtained results showed that under simulated reservoir ...
[ 3 ] - مدل سازی سه بعدی عملکرد پیل سوختی غشای تبادل پروتون با هدف کاهش اتلاف هیدروژن
در پژوهش حاضر، مدل سازی عددی پیل سوختی با الگوی جریان همسو و ناهمسو، به منظور بررسی میزان تأثیر متغیرهای عملیاتی بر عملکرد آن مورد توجه قرار گرفته است. در مدل در نظر گرفته شده، معادله های پیوستگی، اندازه حرکت، انتقال جرم، سرعت واکنش های الکتروشیمیایی و بار الکتریکی در طول کانال پیل سوختی پلیمری در سه بعد نوشته شده و به صورت همزمان با استفاده از روش عددی عنصر محدود حل شده اند. نتایج حاصل از مدل ...
