Top view of two geometries of microchannels considered for hydrodynamic experiments, and the corresponding pressure line. The pressure line obeys the Bernoulli principle. When a sufficiently high velocity is reached in the constriction, the pressure falls below Pvap and bubbles can growth. Downstream, the velocity decreases and the pressure recovers a higher value.
