Journal ArticleDOI
Modes of reaction front propagation from hot spots
TL;DR: In this paper, the results of computations with detailed chemical kinetic schemes for the autoignition of stoichiometric H2CO-air and H2-air mixtures at high pressure and high temperature are reported, with and without a single hot spot.
Journal ArticleDOI
Velocity boundary condition at solid walls in rarefied gas calculations
TL;DR: It is shown that these "Maxwell-Burnett" boundary conditions are in reasonable agreement with the limited experimental data available for Poiseuille flow and can also predict Sone's thermal-stress slip flow-a phenomenon which cannot be captured by conventional slip boundary conditions.
Journal ArticleDOI
A high-order moment approach for capturing non-equilibrium phenomena in the transition regime
Xiao-Jun Gu,David R. Emerson +1 more
TL;DR: In this paper, the theory of regularized moment equations is extended to 26 moment equations for planar Couette and Poiseuille flows, which can correctly predict the Knudsen layer, the velocity profile and the mass flow rate of pressure-driven PoISEUille flow up to 1.0 and capture the bimodal temperature profile.
Journal ArticleDOI
Continuous cell washing and mixing driven by an ultrasound standing wave within a microfluidic channel
TL;DR: The acoustically-driven cell transfer and mixing procedures described may be particularly appropriate for the increasingly complex operations required in molecular biology and microbiology and especially for their conversion to continuous flow processes.
Journal ArticleDOI
Lattice Boltzmann simulation of rarefied gas flows in microchannels
TL;DR: The Maxwellian scattering kernel is adopted to address the gas molecule and surface interactions with an accommodation coefficient (in addition to the Knudsen number) controlling the amount of slip motion and the simulation results of the present LBE model are in quantitative agreement with the established theory in the slip flow regime.
