Hybrid Atomistic-Continuum Fluid Mechanics

Werder T., Walther J.H., Kotsalis E., Gonnet P., Koumoutsakos P., ETH Zürich, CH

We outline a multiscale algorithm for the simulation of dense uids that couples molecular dynamics and continuum fluid dynamics. The coupling between the two models is realized by a common overlap domain and by the [...]

Dynamics in a Thermal Ink Jet: A Model for Identification and Simulation

Rembe C., aus der Wiesche S., Hofer E.P., University of Ulm, DE

In this paper a newly developed model for identification and simulation of dynamic phenomena in a thermal ink jet is presented. As a result of the modeling the calculation of the pressure propagation in the [...]

Modeling 3-D Fluid Flow for a MEMS Laminar Proportional Amplifier

Athavale M.M., Li H.Y., Przekwas A.J., Piekarski B.H., Zeto R.J., Tenney S.M., CFD Research Corporation, US

Fluid flow in a microfluidic laminar proportional amplifier (LPA) was simulated using an advanced 3-D flow solver, CFD-ACE+. Pressure gains for single-stage and two-stage blocked output LPAs were calculated under a variety of flow conditions [...]
