文摘

Wake field has little impact on bubble dynamics at low heat flux in microgravity. Liquid flow caused by wake-effects promotes bubble release at moderate heat flux. Vapor columns form and merge with departure bubble before release at high heat flux. Interaction between microstructure and wake-effects can enhance heat transfer. Theoretical analyses show that bubble is constantly influenced by wake field.
