Abstract
In this study, we have a numerical study on vapor absorption into aqueous LiBr solution in a liquid-gas ejector using convergent nozzle. A model of heat and mass transfer process in absorption of water vapor into a lithium bromide solution in liquid-gas ejector was developed. The model can predict vapor entrainment rate and mass fluxes. The effect of operating condition has been investigated. It has been observed that the absorption mass flux and the vapor entrainment rate increase as the mass flow rate of the inlet solution increases, the inlet solution concentration increases, the inlet solution temperature decreases and the absorber pressure increases. In our results, we get that the mass flux and vapor entrainment rate increases with the mass flow rate, inlet solution concentration, absorber pressure; the mass flux and vapor entrainment rate increases as the inlet solution temperature decreases; the mass flux rapidly decreases at first and slowly to zero value along flow direction.
