The liquid mass flow rate, air velocity and nozzle radius influence the radius and spatial/temporal frequency of liquid beads. The liquid flow rate and air velocity are the two primary factor affecting heat exchanger effectiveness rather than liquid flow patterns. The liquid flow pattern only affects the individual bead-to-air heat transfer coefficient.
