abstract

Recently, electrokinetic flows have raised the interest of scientific community. Driving flow with an electric field leads to promising applications for mixing, concentration and pumping application in lab on chip. However, current models are still inaccurate and in many cases dont fit the measured data. The work presented here is mainly focused on AC electrothermal flows (ACET) carried out in microwells. An AC electric field is applied between 3 interdigitated gold electrodes. Using μPIV (μ Particle Image Velocity) vortex flows are characterized. The competition between light induced (LEF), AC induced electrothermal (ACET) and buoyancy flows (BF) is discussed. Based on those experimental observations, a new theory is tackled. It takes into account the observed instability like behaviour and the discrepancy of the voltage influence on velocities at high conductivity.
