...Yuhao Lin; Junye Li; Jia Sun; Wei Li; Yanlong Cao The combination of microstructured surface and microchannel flow boiling is expected to solve the thermal management problems of high-heat-flux devices. In this study, the experimental investigation of subcooled flow boiling in a high aspect ratio...

.... Subcooled flow boiling experiments were carried out to study the hydraulic and thermal transport performance in a single narrow rectangular microchannel. High-speed flow visualizations were conducted coupled with instrumental measurements to illustrate the effects of heat flux and mass flux on heat transfer...

... vapor bubble generated under subcooled flow boiling conditions. Experiments have been performed in a rectangular channel for a wide range of heat fluxes (q" = 20–50 kW/m 2 ), subcooling level (ΔT sub = 2–9 K), and Reynolds numbers (Re = 600–6000) with water as the working fluid. Results show a strong...

...Wei Li; Zengchao Chen; Junye Li; Kan Zhou; Zhaozan Feng An experimental investigation of subcooled flow boiling in a high-aspect-ratio, one-sided heating, silicon-based rectangular microchannel was conducted utilizing de-ionized water as the working fluid. The microchannel was 5.01 mm wide and 0.52...

... the same operating conditions, the ONB is quite different when a different heating method is used. When the ONB point is considered, the two-side heating of subcooled flow boiling cannot be simply simulated under the one-side heating condition...

...Nilanjana Basu; Gopinath R. Warrier; Vijay K. Dhir A mechanistic model for wall heat flux partitioning during subcooled flow boiling proposed in Part I of this two-part paper, is validated in this part. As the first step of the validation process, the developed model was applied to experimental...

...Nilanjana Basu; Gopinath R. Warrier; Vijay K. Dhir In this work a mechanistic model has been developed for the wall heat flux partitioning during subcooled flow boiling. The premise of the proposed model is that the entire energy from the wall is first transferred to the superheated liquid layer...
