Abstract
In many applications where it is desired to distribute a liquid onto a surface at a very small angle of incidence, it will be necessary to reduce the momentum of the droplets to prevent ricochet off the surface. Obvious methods such as using a restrictor, reducing the operating pressure, etc. are not satisfactory due to the inadequate flow, susceptibility to clogging, etc.
