Definition
Bubble dynamics in a microchannel refers to the nucleation of a bubble on heated flow channel walls and its subsequent interaction with the single-phase or two-phase flow field. Subcooled flow boiling refers to the boiling process with the mean flow enthalpy below the saturated liquid enthalpy at the local pressure, while saturated flow boiling refers to the boiling process with the mean flow enthalpy at or above the saturated liquid enthalpy but below saturated vapor enthalpy at the local pressure.
Overview
The formation and subsequent growth of a vapor bubble on a heated wall covered with a liquid is controlled by the forces arising from the excess pressure inside the bubble, the surface tension forces at the liquid–vapor interface and at the contact line formed by the interface at the heater surface, and the inertia forces resulting from the motion of the flow as well as the interface. The...
