System Performance Evaluation with SystemC for Two PCR Microelectrofluidic Systems

Zhang T., Chakrabarty K., Fair R.B., Cadence Design Systems, Inc., US

We present a performance comparison between two types of microfluidic systems - continuous-flow systems and droplet-based systems. The comparison based on a specific microfluidic application - a polymerase chain reaction (PCR) system. The modeling and [...]

Novel Microfluidic Jet Deflection: Significant Modeling Challenge with Great Application Potential

Delametter C.N., Trauernicht D.P., Chwalek J.M., Eastman Kodak Company, US

A novel method is described for deflecting a liquid jet emanating from an orifice having a diameter of approximately ten microns. While awkward mechanical valves or unwieldy electrodes can be used to deflect a jet, [...]

Numerical Modeling of Ferrofluid Flow Instabilities in a Capillary Tube at the Vicinity of a Magnet

Berthier J., Ricoul F., LETI, FR

The use of ferrofluids is now foreseen to be important for microfluidic systems and biotechnological microsystems as microvalves, micropumps or for the control and synchronization of the flow. The advantage lies in the possibility of [...]

Numerical Analysis of a Microfluidic Oscillator Flowmeter Operating with Gases or Liquids

Simões E.W., Furlan R., Pereira M.T., Laboratório de Sistemas Integráveis - Escola Politécnica da Universidade de São Paulo, BR

We analyzed microfluidic oscillators operating with liquids (water, isopropilic alcohol, and acetone) or gases (nitrogen, argon, and carbon dioxide), using numerical simulation. The possible applications include rapid measurement and control of low fluid flows in [...]

Direct Numerical Simulation of Moving Charged, Flexible Bodies with Thermal Fluctuations

Patankar N.A., Northwestern University, US

The interaction of sub-micron scale objects with fluids is an important problem encountered in miniaturized systems. Various physical phenomena should be modeled simultaneously for a fundamental investigation of these systems. Our objective is to develop [...]

Transient Analysis of Electroosmotic Flow in Nano-diameter Channels

Qiao R., Aluru N.R., University of Illinois at Urbana-Champaign, US

Transient analysis of electroosmotic flow in a nano-diameter channel is presented. The time for flow to reach steady state in a nano-diameter channel for various Debye lengths is investigated by solving the Navier-Stokes equations in [...]

Numerical and Analytical Studies of AC Electric Field in Dielectrophoretic Electrode Arrays

Feng J.J., Krishnamoorthy S., Chen Z.J., Makhijani V.B., CFD Research Corporation, US

Manipulation of micro-sized particles and biological cells using dielectrophoresis (DEP) is an emerging technique in MEMS and nano technology[3]. This paper presents an exact solution of dielectrophoretic motion of a polarized particle in the vicinity [...]
