ABSTRACT:
The present technique provides a system and method for improving atomization in a spray coating device by internally mixing and breaking up a desired coating fluid prior to atomization at a spray formation section of the spray coating device. An exemplary spray coating device of the present technique has a mixture-inducing valve disposed adjacent a flow barrier upstream of a spray formation exit. The mixture-inducing valve may have a variety of blunt/angled structures and internal passages to facilitate fluid mixing. The mixture-inducing valve also may interact with the flow barrier to enhance the fluid mixing and fluid breakup. One embodiment of the present spray coating device has an internal fluid breakup section, such as an impinging jet section, adjacent the mixture-inducing valve. The resulting spray coating has refined characteristics, such as reduced mottling.
