10.2.2.2 Wheel Atomizers
A typical wheel atomizer is shown schematically in
Figure 10.4. Liquid is fed into the center of a rotating
wheel , moves to the edge of the wheel under the centrifugal
force, and is disintegrated at the wheel edge
into droplets. The spray angle is about 1808C and
forms abroad cloud. Because of the horizontal trajectory
these atomizers require large-diameter chambers.
The most common design of the wheel atomizer has
radialvanes.
The linear peripheral speed ranges from 100 to
200 m/s. For the usual wheel diameter, angular speed s
between 10,000 and 30,000 rpm are necessary [15] (see
Figure 10.5).
