Abstract The instability at the interface between two parallel flows of immiscible liquids through a uniform planar pore is studied by using linear stability analysis. A characteristic equation determines growth rate versus wavenumber, and conditions are determined. governed dimensionless group relating ratio gravity to interfacial tension. Interfacial tension has stabilizing effect resisting d...

The sustainable development of oil–gas and petrochemical industries necessitates the cost-effective eco-friendly technologies to treat mass-produced oily wastewater discharge from these industries. This study applied a simple radical polymerization enhance oil adsorption efficiency agricultural waste biomass wheat straw (WS) by grafting biocompatible poly(methyl methacrylate) (PMMA). Diesel oil...

Thermal recovery techniques including Fast-SAGD process increases the production efciency of heavy oil reservoirs. Effective parameters in this study included injection and production rates, height of the injection, production, and offset wells, production and injection cycles, and pressure of the offset wells. In this study, optimization studies were performed. The objective function was defned a...

The objective of this study was to examine the interaction of cardiopulmonary bypass venous air with assisted venous drainage, focusing on its production of gaseous microemboli in the arterial line. An in-vitro recirculating cardiopulmonary bypass circuit containing fresh whole bovine blood was monitored with a pulsed-doppler microbubble detector. Air of specific amounts was injected into the v...
