Abstract

This paper reports an experimental study on the vapour absorption process with an aqueous lithium bromide solution based nanofluid. It is a comparison study to investigate the effect of the nanofluid (base fluid + nanopowders) and the nanofluid under the influence of an external magnetic field. It is found that the vapour absorption rate increases using the nanofluid and applying the magnetic field to the nanofluid can further enhance the vapour absorption process. The vapour absorption rate is 1.53 and 1.67 times higher at the solution flow rates 3L min-1 and 3.5L min-1 , respectively. The enhancement correlates with the frequency of nanoparticles movement induced by the external magnetic field. The limited experimental results suggest that the high frequency of the nanoparticles' movement benefits the vapour absorption process.
