Influence of microflow on hepatic sinusoid blood flow and red blood cell deformation
TL;DR: In this article, an immersed boundary method coupled with a lattice Boltzmann method was adopted in an in-vitro hepatic sinusoidal model, and flow field and erythrocyte deformation analyses were conducted by introducing three new source terms including permeability of the endothelial layer, resistance of hepatocyte microvilli and collagen layers, and deformation of red blood cells (RBCs).

Two-layer nanofluid flow and heat transfer in a horizontal microchannel with electric double layer effects and magnetic field
Qingkai Zhao,Hang Xu,Longbin Tao +2 more
TL;DR: In this article, the authors investigated the immiscible two-layer heat fluid flows in the presence of the electric double layer (EDL) and magnetic field, and showed that increasing the EDL thickness and Hartmann number can restrain the fluid flow.

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.
