Micro Polymer Capsule Constructed with Micro Pillars Formed by Multi Laminating Method

Plasticity of Nano- and Micro-pillars

We review unique mechanisms of plastic deformation in nanoand micropillars. At the nanoscale, it is shown that plastic deformation is asymmetric with respect to direction of mechanical loading, as a result of specific relationships between the normal and resolved shear stress on active slip planes. This is attributed to the dependence of shear wave speed on the stress state acting on slip plane...

Creeping Flow through Microchannels with Integrated Micro-pillars

Pressure drop through micro-pillar-integrated mini/microchannels is studied experimentally and analytically. Following our previous studies, the low aspect ratio micropillars embedded in a microchannel are modeled as a porous medium sandwiched between channel walls. The pressure drop is expressed as a function of the salient geometrical parameters such as channel dimension, diameter and spacing...

Simulation of Micro-Channel and Micro-Orifice Flow Using Lattice Boltzmann Method with Langmuir Slip Model

Because of its kinetic nature and computational advantages, the Lattice Boltzmann method (LBM) has been well accepted as a useful tool to simulate micro-scale flows. The slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. The most used slip boundary condition is the Maxwell slip model. The results of Maxwell slip model are affected by the ac...
