Analysis of Steam Absorption by a Subcooled Droplet of Aqueous Solution of LiBr

Adiabatic water absorption properties of an aqueous absorbent at very low pressures in a spray absorber

“…It is known that as the size of these droplets decreases, the total area exposed to the vapor increases and the rate of absorption increases accordingly. Benberhim et al [1], Summerer et al [2], Morioko et al [3] and Ryan [4] confirmed the above effects with experiments, analytical and numerical calculations. Those studies show that replacing a conventional absorber with a spray absorber and enhancing the mass transfer process is practically feasible.…”

Experimental study on the adiabatic absorption of water vapor into LiBr–H2O solutions

“…The adiabatic absorption process has been frequently proposed for chillers and heat pumps as an alternative to the traditional concept of cooled absorption [1][2][3]. In this approach the evaporated refrigerant is absorbed by a flow of solution, substantially sub-cooled and appropriately distributed inside an absorption chamber, without evacuating the released heat to any external fluid, i.e.…”

“…In 1992 Morioka et al [2] solve the coupled diffusion equations for the same geometry and the same boundary and initial conditions, but including internal circulation at low Reynolds numbers (Re < 10) within the droplet, originated by shear forces. Results show a significant increase in the absorption rate due to this motion.…”

Experimental assessment of vapour adiabatic absorption into solution droplets using a full cone nozzle

“…The first reported numerical models include those of Morioka et al [26] and Lu et al [27]. In both cases, the absorption of water vapour by water-lithium bromide solution spherical droplets is analysed when experiencing internal circulation, which is driven Simultaneous internal heat and mass transfer during absorption of ammonia vapour by ammonia-lithium nitrate solution drops was modelled by Venegas et al [28].…”
