“…This observation may reveal that the rough surface at the interface can disconnect possible macro paths or more meandrous micro paths, which take for time for the fluid to move at the interface. A similar observation was reported by other researchers [30]. Running CFD analysis and X-ray CT techniques can help to understand the micro annular path's direction and size.…”

In this experimental study, two different cementitious materials including (i) a class of expansive cement currently used for plug and abandonment (P&A) operations, and (ii) a non-cement-based naturally occurring rock, known as geopolymer are selected to examine the hydraulic bond strength and shear bond strength. Clean machined steel and rusty corroded steel were selected to represent the casing. The test samples were cured at 90 °C considered as bottom-hole static temperature (BHST) and under elevated pressure of 17.2 MPa for one week. The hydraulic sealability of the barrier materials tested up to 3.4 MPa of differential pressure. The results indicated that additives used in slurry preparation impact the hydraulic sealability of the material. Additionally, the rusty corroded streel provided a better hydraulic sealability comparing to the clean machined steel for the same cementitious material. The shear bond strength test was performed by running the push-out test. According to the present test observations, no correlation was found between the shear bond and hydraulic bond strength of different barrier materials. The geopolymer showed the lowest shear bond strength, while it provided the highest hydraulic sealability.

“…As we mentioned, nanofluids have several uses in engineering and industry applications. For complex geometries, real flows are governed by a set of nonlinear equations [25,26]. Therefore, numerical approaches have been used to find suitable and acceptable solutions, like macroscopic methods (finite volume (FVM), finite difference(FDM), and finite element (FEM) methods) and mesoscopic method (Lattice Boltzmann (LBM)).…”

Recently, nanofluids have been used as an alternative in several industries to improve the heat transfer process. This paper focuses on the numerical modeling of the performance of the natural convection process through TiO₂/Al₂O₃-water nanofluids in a square cavity containing a heated block. The lattice Boltzmann method is used in this study to present the nanofluid heat transfer enhancement. Results are presented in terms of streamlines, isothermal contours, and Nusselt number profiles. The findings demonstrate that by raising the Rayleigh number and solid nanoparticle concentration, the average Nusselt number increases, and they reveal that the heated block enormously affects the flow structure and heat transfer. It is also demonstrated that the type of nanoparticles significantly impacts the natural convection heat transfer.
