Convective heat transfer in microscale slip flow
A. Guvenc Yazicioglu,Sadik Kakac +1 more
TL;DR: In this paper, steady-state convective heat transfer in different microchannels (microtube and parallel plates) was presented in the slip flow regime, in which rarefaction, axial conduction, and viscous dissipation effects were taken into consideration.
Friction stir channeling: An innovative technique for heat exchanger manufacturing
TL;DR: In this paper, the defect formation and material flow are controlled during the FSW/P. Friction stir channeling (FSC) is one such adaptation of FSP that can produce continuous and stable internal channels for application in heat exchanging equipment.

Microchannel Heat Transfer
C. W. Liu,H. S. Ko,Chie Gau +2 more
TL;DR: In this article, it has been recognized that for flow in a large scale channel, the heat transfer Nusselt number, defined as hD/k, is a constant in the thermally developed region where h is the convective heat transfer coefficient, k is thermal conductivity of the fluid and D is the diameter of the channel.
