Influence of African American Engineering Student Perceptions of Campus Climate on Graduation Rates

TL;DR: In this article, the authors investigated student perceptions of institutional and personal/social campus climate factors to determine how these perceptions influence academic performance and institutional graduation rates, and found that students at higher of the academic selectivity categories had higher graduation rates.
Journal ArticleDOI

Molecular dynamics simulation of the equilibrium liquid–vapor interphase with solidification

TL;DR: In this paper, the equilibrium structure of the interphase interfacial region that exists between a liquid film and a bulk vapor is resolved by molecular dynamics simulation, which involves counting of neighboring molecules and comparing the results with boundary criteria that permit the boundaries to be precisely established.
Journal ArticleDOI

Atomistic hybrid DSMC/NEMD method for nonequilibrium multiscale simulations

TL;DR: A multiscale hybrid method for coupling the direct simulation Monte Carlo (DSMC) method to the nonequilibrium molecular dynamics (NEMD) method is introduced, determined that wetting effect strength and solid molecular mass have a significant impact on the energy transfer between gas and solid phases and thermal accommodation coefficient.
Journal ArticleDOI

Multiscale molecular simulations of argon vapor condensation onto a cooled substrate with bulk flow

TL;DR: In this paper, a hybrid simulation method is employed to study the condensation of saturated argon vapor flowing tangentially across a stationary cooled substrate, at nanoscale resolution, combining a direct simulation Monte Carlo treatment of the bulk vapor phase with a nonequilibrium molecular dynamics treatment of condensed liquid and interphase regions; it provides an efficient simulation procedure for a heterogeneous system with a large ratio of vapor to liquid length scales.
Journal ArticleDOI

Dynamics of microscale shock/vortex interaction

TL;DR: In this article, the mutual interactions of impinging planar shocks of up to Mach 3 with transverse microvortices having core sizes comparable to the thickness of the shock were investigated.
