CFD of roughness effects on laminar heat transfer applied to additive manufactured minichannels
TL;DR: In this paper , the impact of roughness on the thermo-fluid characteristics of laminar forced convection in rough minichannels was investigated, where a numerical model was developed to create 3D Gaussian roughness with specified root-mean-square height.
Heat transfer characteristics of hydrid microjet-microchannel cooling module
TL;DR: In this article, the performance of a microjet-microchannel cooling module was investigated under steady state conditions for single phase liquid cooling. But, the main objective of this paper was to experimentally investigate the heat transfer intensification in a micro jet-micro channel cooling module.

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.
