摘要: Abstract A visual study of bubble departure size in forced convective subcooled boiling flow under static and heaving conditions was presented. High-speed digital images phenomena were obtained, which used to measure diameter. Experiments conducted at atmosphere pressure a narrow rectangular channel, with mass flux ranging from 300 710 kg/m 2 s, heat 65 298 kW/m inlet subcooling 20 40 K. The frequency, is generated by six degrees-of-freedom platform, ranged 0.2 0.61 Hz. results indicated that decreasing increasing had tendency increase diameter condition. In motion, affected additional acceleration rate fluctuation. model proposed predict the considering agreed well experimental data within averaged relative deviation ±17.5%.
