The effects of ejector adiabatic absorber on heat and mass transfer of binary nanofluid with heat transfer additives

Abstract This paper presents experimental results on the study of effects ejector adiabatic absorber heat and mass transfer binary nanofluid with additives (2-ethyl-1-hexanol gum Arabic). In this case, H 2 O/lithium bromide-alumina was suggested due to a growing interest in absorption working fluid for solar energy application. An setup — test rig designed absorption, heat, rate as result refrigerant vapour flow entrained by absorber. The carried out at different solution flowrate (0.051 0.17 kg/s) three prepared sample solutions, which include pure LiBr solution, LiBr-Alumina without additives, additives. rate, coefficient, coefficient samples were reported. On other hand, percentage enhancements all parameters suitable 0.085 kg/s addition alumina recorded. 25% 96%, enhancement rates recorded 20% 82%, 85% 183%, obtained 72% 156% nanoparticles only respectively. Material balance analysis suggests that inflow equals outflow from ejector, indicating complete beyond falling film can occur concentration. article also evidence capability strong absorber, component, earlier reported using numerical models.
