| Research Abstract |
To develop a high performance liquid-liquid direct contact evaporator, following four kinds of injection nozzle of evaporation liquid were tested. (1) A nozzle with a porous medium in its inner surface. (2) A nozzle consfructed by a porous medium pipe through which evaporation liquid pass. (3) A nozzle with a electric heater in its inner space. (4) A nozzle impressed ultra-sonic vibration. To evaluate the evaporating performance of these nozzles. mesurements of the temperature profiles in the evaporator were performed by using the micro-thermocouple. These mesurements show the progress of evaporation process along the flow direction of the evaporator. As a results of testing these nozzles, stable evaporation were continued for the nozzle (1), (2) and (3) in very low temperature differeces about 3 K.For the nozzle (4), enhancement of evaporation was not appeared.
