Wettability alteration is one of the most important methods for oil recovery from sandstone and carbonate reservoirs. The effects of salinity, pH, temperature, and chemicals such as surfactants and fatty acids on the alteration of the wettability were described in previous studies. In recent years, attention has been directed to nanoparticles as a wettability alteration agent. The effect of som...

This paper scrutinizes the nonlinear multibubble model with considering bubble-bubble (BB) interaction in Cu?Al2O3/water hybrid nanofluid over vapour bubble radius Newtonian mediums. Firstly, we present derivation of extended Rayleigh-Plesset (ERP) equation under effect BB nanofluids based on Navier-Stokes equation. The is formulated by continuity equation, ERP and relations thermophysical feat...

In this paper, the natural convection heat transfer of Al2O3-EG-water nanofluid in a rectangular cavity which is heated from the bottom and is cooled from the top has been investigated numerically. The governing equations for a Newtonian fluid have been solved numerically with a finite volume approach using the SIMPLER algorithm. The main focus of the current study is on the effects of variable...

in this paper, turbulent mixed convective heat transfer of water and al2o3 nanofluid has been numerically studied in a horizontal tube under non-uniform heat flux on the upper wall and insulation in the lower wall using mixture model. for the discretization of governing equations, the second-order upstream difference scheme and finite volume method were used. the coupling of pressure and veloci...

Enhanced oil recovery using nanoparticles is a promising method. However, when injected into reservoir, can block pores and cause permeability damage. Therefore, enhancing their performance to lower the damage effect crucial. This study investigated of pH alteration through carbon dioxide (CO2) injection on limestone caused by an aluminum oxide (α-Al2O3) nanofluid. The methodology involved nano...

 The forced convection heat transfer of turbulent Al2O3-water nanofluid flow inside the grooved tubeswith the different aspect ratio of the rectangular grooves is numerically investigated. The governingequations have been solved using finite volume method (FVM) coupled with SIMPLE algorithm. It isassumed the heat flux is constant on the grooved walls. The Single-phase approach is applied for th...

In this study, the convective heat transfer and pressure drop in laminar flow of Al2O3/water and CuO/water nanofluids through square and triangular cross-sectional ducts have been numerically investigated using new technique. It has been assumed that there is constant heat flux boundary condition at walls. In addition, to include the presence of nanoparticles, the dispersion model has been used...
