Enhancement of bubble absorption process using a CNTs-ammonia binary nanofluid

Effect of nanoparticles on oxygen absorption enhancement during sulfite forced oxidation

“…Seyf and Nikaaein [17] investigated the effects of nanoparticle size and the particle Brownian motion on the thermal performance of nanofluid flow in micro-channel heat sink. However, there is no good theory to explain the effect of nanoparticles on the gas-liquid mass transfer [18,19], so further investigations are urgently needed.…”

Experimental study of CO 2 absorption in aqueous MEA and MDEA solutions enhanced by nanoparticles

“…Inhibition of bubble coalescence considers that fine particles could change the gas-liquid contact area to affect the mass transfer flux, but it is not clear for the impact on the mass transfer coefficient. Generally, comprehensive and acceptable theory is lack for explaining the effect of nanoparticles on the gas-liquid mass transfer (Kim et al, 2006;Ma et al, 2009), and thus further investigations are in great need.…”

Nanofluids

“…Diffusionthermo implies that heat transfer is induced by concentration gradient [71]. Ma et al studied the mass transfer process of absorption using CNTs-ammonia nanofluids as the working medium [72,73]. The absorption rates of the CNTs-ammonia binary nanofluids were higher than those of ammonia solution without CNTs.…”
