A Review of the Complex Flow and Heat Transfer Characteristics in Microchannels
TL;DR: In this article , the authors systematically review the research about microscale flow and heat transfer, focusing on the flow-and heat-transfer mechanisms in microchannels, which is elaborated in the following two perspectives: one is the microscale single-phase flow that only considers the influence of scale effects, the other is the special heat transfer phenomena brought about by the coupling of micro-scale flow with special fluids (fluid with phase change (pseudophase change)).

Thermodynamic analysis of capillary flows in the presence of hydrodynamic slip
A. Laouir,D. Tondeur +1 more
TL;DR: In this article, a thermodynamic description of liquid flows in capillaries with hydrodynamic slip at the solid-liquid interface is given, and the main result concerns the existence of a capillary pressure of slip; slip occurrence leads to a pressure decrease in the flow and might cause cavitation.
