32. When the step at the channel outlet is negligible (the ratio of the well height to the channel height is nearly 1), the to-be-dispersed phase that passed through the channels flows out continuously, and droplet generation from the channels does not occur. When the well depth is close to the resultant droplet diameter (the ratio of the well height to the channel height is typically 3 or more), mostly spherical droplets are generated from the channels.
