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. ...
Small-scale anisotropy in turbulent shearless mixing.
The generation of small-scale anisotropy in turbulent shearless mixing is numerically investigated. Data from direct numerical simulations at Taylor Reynolds' numbers between 45 and 150 show not only that there is a significant departure of the longitudinal velocity derivative moments from the values found in homogeneous and isotropic turbulence but that the variation of skewness has an opposit...
متن کاملEffect of Surface Roughness on Small-Scale Velocity and Scalar Characteristics in a Turbulent Channel Flow
Using DNS data in a turbulent channel flow, the paper examines the effect of the surface geometry on the vorticity and (passive) scalar gradient vectors at a relatively small Reynolds number and for a molecular Prandtl number of 1. While a strong correlation between these two vector fields is expected close to the wall when the latter is smooth, significant changes occur when the surface is mod...
متن کاملSmall-Scale Mixing of the Elements
The progressive mixing and contamination of interstellar gas by supernovae and other processes following the passage of a spiral density wave is reviewed, with an emphasis on the Solar neighborhood. Regions of star formation should begin their lives with an inhomogeneous mixture of abundances as a result of their chaotic and large-scale formation processes. These inhomogeneities should continue...
متن کاملEffect of Socio-Economic Characteristics on Food Security of Small Scale Farmers in Rawalpindi
About half of the population in Pakistan is food insecure. The study focused the food secure population and the strategies for reducing poverty in district Rawalpindi. The study was carried out in district Rawalpindi in the Punjab province of Pakistan. Simple random sampling technique was used for this research study in district Rawalpindi. A sample of 120 respondents was selected. Then the dat...
