The effect of microbubble emission boiling (MEB) on the mixing of two fluids in a microfluidic device was studied experimentally. When MEB occurred on an electric heater made of a platinum wire with a diameter of 30 micrometers, the mixing of the two fluids increased markedly. However, nucleate boiling had no significant effect on the mixing. A high-speed video showed that the very rapid growth and collapse of micro boiling bubbles on the heater causes the strong mixing of the two fluids. The coexistence of highly superheated and highly subcooled water near the heater seems to be the reason for such enhanced mixing.

在微流体装置中通过微泡发射沸腾增强混合

实验研究了微气泡发射沸腾 (MEB) 对微流体装置中两种流体混合的影响。当 MEB 发生在直径为 30 微米的铂丝制成的电加热器上时，两种流体的混合显着增加。然而，核沸腾对混合没有显着影响。一段高速视频显示，加热器上微沸腾气泡的快速增长和破裂导致两种流体强烈混合。加热器附近高度过热和高度过冷水的共存似乎是这种混合增强的原因。
