Roughness effect on flow and thermal boundaries in microchannel/nanochannel flow using molecular dynamics-continuum hybrid simulation

Miniaturization featuring rapid improvements of MEMS/NEMS has become a revolutionary trend in various engineering fields. The interfacial characteristic is crucial in micro/nanofluidics for a brand new multi-scale/trans-scale understanding bridging the microscopic phenomena and macroscale rules. A novel molecular dynamics-continuum hybrid simulation method has been proposed and successfully implemented. The work reveals that the macroscopically negligible roughness plays significant role in boundary conditions in micro/nanochannels.
