Single Bubble Dynamics on a Vertical Wall in Sub-cooled Nucleate Boiling
Sarker, D.; Franz, R.; Hampel, U.;
Nucleate boiling heat transfer is an efficient way of heat transfer for many engineering applications, like heat exchangers, boilers, electronic cooling systems etc. Therefore, heat transfer enhancement in the nucleate boiling region has received continuous interest for a long time. For the further enhancement of heat transfer performance, fundamental physics of bubble growth and departure process should be revealed clearly. In the current study, high resolution optical instrumentation and highly efficient parallel DNS (Direct Numerical Simulation) solver are used to investigate the single bubble dynamics. Numerical results are validated against experimental results of subcooled nucleate boiling in water at atmospheric pressure, where the heated surface was vertically oriented.
Keywords: subcooled nucleate boiling; single bubble; vertical heater
