Figure 2
(a) Three-dimensional rendition of measured velocity fields. Inner and outer diameters of the two crossed tubes are shown (open circles). Arrows represent the flow vectors; length and color of the vector denotes the speed. The color bar shows the speed in µm s−1. (b) Projected velocity on the xy plane. The arrows represent the velocity vectors in the xy plane; length and color of the vectors represent the in-plane speed. Color bar speed units are µm s−1. Open circles denote the inner and outer diameters of the tubes. |
