Jet Flows from Bubbles During Subcooled Pool Boiling on Micro Wires
http://www.paper.edu.cn Science in China Ser. E Engineering & Materials Science 2005 Vol.48 No.4 385—402 385 Jet flows from bubbles during subcooled pool boiling on micro wires WANG Hao, D. M. Christopher, PENG Xiaofeng & WANG Buxuan Laboratory of Phase Change and Interfacial Transport Phenomena, Department of Thermal Engineering, Tsinghua University, Beijing 100084, China Correspondence should be addressed to Peng Xiaofeng (email: [email protected]) Received January 4, 2005 Abstract An experimental investigation was conducted on subcooled nucleate boiling on ultra-small wires having diameters of 25―100 µm. High-speed photography and laser PIV (Particle Image Velocimetry) technology were used to visually observe the bubble dynamics. For highly subcooled boiling at moderate heat fluxes, the bubbles generally remained attached to the micro heating wires and bubble-top jet flows were clearly observed. Smaller bubbles usually had stronger bubble-top jet flows, while larger bubbles seemed to produce multi-jet flows. The structures of the bubble-top jet flows, as well as multi-jet flows, were proposed from the experimental observation. A model was developed to describe jet flow phenomena from bubbles on micro wires. Numerical simulations for bubbles having diameter of 0.03 and 0.06 mm showed that both the bubble-top and multi-jet flows were induced by a strong Marangoni effect due to high temperature gradients near the wire. The predicted velocity magnitudes and flow structures agreed very well with experimental measurements. The bubble size relative to the wire is an important factor affecting the jet flow structure. For a 0.03 mm bubble on a 0.1 mm wire, only a bubble-top jet flow forms, while a complex multi-jet flow pattern forms around the bubble with a weak bubble-top jet and two side jet flows for a 0.06 mm bubble. -

Rapid advances in space science and thermal insulation technology as well as the broad use of new energy and energy-saving materials require that the thermophysical properties community achieve significant improvements in both theoretical research and experimental research to facilitate application of advanced technologies in nearly all fields. So today, we are honored to provide a forum for the researchers, scientists and practitioners from all over the world to exchange information, present new ideas, and discuss the future directions and priorities in the areas of thermophysical properties. Beijing was the birthplace of Asian Thermophysical Properties Conference which was proposed by Professor Bu-Xuan Wang (Academician of the Chinese Academy of Sciences, Professor of Tsinghua University, China) and Professor N. Seki (Professor of Hokkaido University, Japan). The eight previous Asian Thermophysical Properties Conference originated from 1986 enhanced the international dissemination of recent advances in thermophysical properties research. The International Organizing Committee seeks to carry on the valuable international exchange of new information and ideas in this field for the 21st century by organizing the SYMPOSIUM in Asia every three years. Those good effects of the eight former symposiums took us great proud: A large number of papers were presented describing significant advances in thermophysical properties research globally. -
