Transient response of thermocapillary pumping of a droplet in a micro heat engine

TL;DR: In this paper, a new analytical model is developed to predict the transient velocity and voltage generated due to thermocapillary pumping in a micro heat engine (MHE), which uses lead zirconate titanate (PZT) as a substrate for the MHE.

Boundary layer theory

TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.

Experimental Investigation on Liquid Forced-Convection Heat-Transfer Through Microchannels

TL;DR: In this paper, the authors investigated the single-phase forced-flow convection of water or methanol flowing through microchannels with rectangular cross-section and found that the fully developed turbulent convection regime was initiated at about Re = 1000-1500.
