Zusammenfassung
An experimental pilot scale three-phase, direct-contact heat exchanger was constructed and tested. Experiments were performed using normal pentane as the dispersed phase and water as the continuous phase. The inlet water temperatures ranged from 75 to 88°C, and the inlet pentane temperatures varied from 23 to 38°C. The volumetric heat transfer coefficient, hold-up and heat flow-rate are functions of pentane mass flow-rate. For high pentane/water volumetric flow ratios flooding was reached. Before reaching flooding conditions, accumulation of liquid pentane at the top of the active volume was found. The experimental volumetric heat transfer coefficient values are on average 30\% greater than those estimated with the correlation previously proposed by Jacobs.
