| Abstract |
The present study predicted the effect of the flow rate of coolant on the ab-sorption performance of a vertical falling film type absorber. Heat and mass transfer perform-ances were numerically investigated. The exit temperatures of solution and coolant were de-creased as the flow rate of the coolant was increased at the film Reynolds number of 100. The absorption mass flux was increased and then decreased as the distance from the inlet of the absorber was increased. The distance showing the maximum absorption mass flux was ranged from 0.3 to 0.5m. The heat flux and the absorption mass flux were increased and then slowly decreased as the flow rate of the coolant was increased. The maximum values were obtained at the flow rate of coolant of 2.0L/min. |
