3-Dimensional fluid flow profile on a structured PDMS surface

We present a device capable of transporting fluid in an open system along a wall without rotating parts using cilia-like comb rows. For the first time, we show a 3-dimensional image of the flow field along the rows with velocity profiles and mid velocities for all three propagation types obtained in our device, symplectic, antiplectic, and synchronous flow. We show the influence of secondary flow on the device. The methods used allows us to simplify our experiment to just a quarter of data.
