When steam bubbles are released into a medium of a hydrophobic coolant, the condensate is scattered through the coolant in the form of tiny droplets. This condensation pattern is unfavorable for direct-contact condensers because it is difficult to separate the condensate and the coolant. This paper proposes a novel bubble-release device by which the condensation pattern is so transformed that the condensate remains within the confines of the bubble wall. An experimental examination with single steam bubbles released into a medium of liquid paraffin is demonstrated.
