Flow of Fiber-Reinforced Cement Slurries at Elevated Temperatures

Cement slurries are used for the construction of oil wells as deep as 30,000 ft (9,000 m). The severe performance requirements for such materials have prompted the search for appropriate fiber reinforcement to improve the slurry’s tensile strength, impact resistance, and fracture toughness, without decreasing its pumpability. A continuum theory for dilute suspensions of large-aspect-ratio parti...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Investigation of the Flow Characteristics of Methane Hydrate Slurries with Low Flow Rates

Gas hydrate blockage in pipelines during offshore production becomes a major problem with increasing water depth. In this work, a series of experiments on gas hydrate formation in a flow loop was performed with low flow rates of 0.33, 0.66, and 0.88 m/s; the effects of the initial subcooling, flow rate, pressure, and morphology were investigated for methane hydrate formation in the flow loop.
