Coupled Multiphysics and Chemistry Simulations of PCR Microreactors with Active Control

Athavale M.M., Chen Z.J., Furmanczyk M., Przekwas A.J., CFD Research Corporation, US

High-fidelity simulation tools that couple fluid flow, heat transfer and chemistry of PCR microreactors have been applied to different microreactor designs. The tools are coupled to a controller software for thermal control of the virtual [...]

Coupled Fluid-Thermal-Structural Simulations in Microvalves and Microchannels

Athavale M.M., Yang H.Q., Przekwas A.J., CFD Research Corporation, US

This paper presents the results of high-fidelity, 3-D simulations of coupled flow, heat-transfer and structural mechanics simulations of microchannels, micropumps, microvalves, and time-accurate simulations of a microoscillator. In each of these cases, the simulated results [...]

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 [...]
