Velocity Profiles for Flow of Omani Crude Oils and Other Liquids

Sayyadul Arafin, S.M. Mujibur Rahman · مجلة جامعة السلطان قابوس للعلوم · 2014 · 10.24200/squjs.vol19iss1pp87-94

Velocity profiles of Newtonian immiscible liquids undergoing laminar flow between two horizontal plates under pressure gradient are investigated using a momentum balance equation. The differential equation describing the flow has been solved and equations for the velocity profiles of a two-layer and three-layer liquid …

Dynamical Properties of Omani Crude Oils for Flow Through a Vertical Annulus and a Cylindrical Pipe

Sayyadul Arafin, S.M. Mujibur Rahman · مجلة جامعة السلطان قابوس للعلوم · 2011 · 10.24200/squjs.vol16iss0pp102-117

We have initially investigated the temperature dependence of density and viscosity of a number of crude oils, collected from various hydrocarbon reservoirs in Oman. The measured data are then utilized to investigate the flow dynamics of these hydrocarbon fluids under gravity and applied pressures at various temperature …

On the Roles of Interatomic Interactions and Coordination Numbers on Einstein Temperatures of 3D Transition Metals

M.A. Khaleque, G.M. Bhuiyan, RI.M.A Rashid وآخرون · مجلة جامعة السلطان قابوس للعلوم · 1997 · 10.24200/squjs.vol2iss0pp65-68

We have investigated the roles of the coordination numbers and interatomic interactions on Einstien temperatures 0e for a number of bee 3d transition metals. We have employed a few of the popular transition metal pseudopotentials in the Calculations aiming at a comparative survey of the roles of these pseudopotentials …
