The objective of this review paper is to implement and investigate of micro‐nano bubble technology for enhancement of condensation heat transfer. Micro‐nano bubbles dispersions in aqueous solutions can stay for a substantial time. As an example, 20 micron size micro‐nano bubbles take daily to rise one meter. Because the inertia force of fluid current exceeds the buoyant force, any currents within a large vessel would be anticipated to entrain kind of micro‐nano bubble dispersion. Micro‐nano bubbles will vaporize hotter water toward the center of the plume and convert that extra heat of transition to the cold wall, where it will condense the vapors and release latent heat if the condenser is arranged in the micro‐nano bubble‐assisted airlift configuration.

Envision a flawless cylinder‐shaped roll of graphene formed into a carbon nanotube (Senthilkumar et al., 2017). A Russian group first created carbon nanotubes in 1952 and published the first transmission electronic microscope (TEM) picture of the tube‐like carbon nanotube made from nanometric‐sized carbon filaments (Senthilkumar et al., 2020).…”

The primary focus of this review article is to investigate the behavior of multi walled carbon nanotubes (MWCNT) suspended in clean water during the boiling heat dispersions (transfer process). With novel nano boiling technique, the convective heat transfer coefficient of nanoparticles in nanofluid, density, viscosity, and thermal conductivity were reviewed. The various research outcomes on MWCNT mixed with water are discussed. Based on various test results, it was evident that adding (MWCNT) raised the boiling heat transfer coefficient of the base fluids.

“…Because nanofluids have improved thermophysical characteristics, they may be employed in a wide range of mechanical and technical applications, including nanofluid coolants for transformer cooling, automotive radiator, computer cooling, electronics cooling, and electronic device cooling (Senthilkumar et al., 2017).…”

The focus of this present investigation is to examine the heating characteristics of gold and silver nanoparticles at different laser wavelengths. Comparative research on the heat transfer studies with gold ultrafine particles and silver ultrafine particles was undertaken to determine an appropriate frequency and substance with greater photothermic effectiveness for hyperthermic use in cancer therapy. At 488 nm and 540 nm, gold nanoparticles are found to be greater photothermally efficient than silver nanoparticles. The 540 nm laser burns gold nanoparticles greater than the 488 nm laser. Silver nanoparticles, on the other hand, showed a slightly lower temperature increase at 540 nm than at 488 nm. In the diametral surface range of 0–50 nm, size‐dependent impact research showed that the absorbance effectiveness of single gold nanoparticulate with larger diameters is larger than those with lower diameters.
