Numerical study on performance enhancement of absorption heat pumps using surfactants.

Author(s) : LEE C. H., HA J. J., KIM S. H.

Summary

In an absorption refrigerating system, it is well-known that water vapour absorption into lithium bromide aqueous solution is enhanced by the addition of surfactants. Marangoni convection plays a role, but its mechanism is not yet clearly understood. In the study, a relation between heat and mass transfer and Marangoni convection was investigated using mathematical modelling and numerical simulation in a falling film type absorber.
