simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
On water vapor transport in field soils
Measurements of soil volumetric moisture content and temperature were made at 2, 4, 7, 10, and 15 cm below the surface of a bare field soil, over a 1-week period at 20-min intervals. The conductive heat and liquid moisture fluxes were calculated for the soil layer 7–10 cm below the surface, and the water vapor flux was then determined from both the energy transfer and mass transfer equations. W...
متن کاملAtmospheric Water Vapor Transport and the Water Balance of North
The atmospheric water vapor flux divergence and certain aspects of the water balance of North America are investigated, using data from the period May 1, 1958-Apr. 30, 1963. The mean vertical distribution of flux divergence is computed for the United States for the months of January (1962, 1963) and July (1961, 1962). Strong flux convergence in the lowest kilometer and divergence in the remaind...
متن کاملThermal Processing of Injection-Molded Silicon Carbide
Silicon carbide is the most important and versatile non-oxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding—removal of organic additives—is the rate-limiting step in P...

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
