Abstract:
Abstract Surface modification of the metal components involved in heat transfer is one of the passive methods used to enhance their heat transfer efficiency. Coatings with micro- or nano-scale features are widely employed to modify surfaces due to their enhanced surface area, which increases the number of boiling nucleation sites, leading to the generation of a higher number of bubbles. In geothermal power generation, due to the aggressive nature of the working fluid and chemistry of the geothermal brine, ceramic coatings are preferred.

Abstract Deviated wellbore regions make cutting transport harder owing to the substantially low annular velocity distribution in these regions. This causes migrating cuttings to deposit on the lower borehole wall, creating cutting beds and thus resulting in drilling problems like pipe sticking. Water-based mud (WBM) that includes nanoparticles (NPs) to remove cuttings still needs further investigation due to the substantial drop in annular velocity of the mud in inclined boreholes.
