摘要：

An optical technique is described which permits the simultaneous determination of detailed microlayer geometry and macroscopic bubble dynamics in nucleate boiling. Boiling takes place from a transparent heating surface forming the floor of a tank. With parallel, monochromatic illumination from below, the microlayers reflect interference patterns similar to Newton's rings. These fringe patterns are recorded by a high-speed ciné camera and provide details of microlayer shape and thickness. Simultaneously, and on the same film, normal bubble-growth pictures in profile are obtained. The optics of the system are analysed. Sample results are discussed. © 1969.
