Abstract
A method and apparatus for droplet generation in agricultural or other spraying comprises supplying air and liquid to a supply chamber (28, 102) having an outlet orifice (38, 114), and entraining the liquid in the air flow for droplet formation. Air and liquid are injected into the supply chamber which has a closed end wall (42, 108) on which the liquid forms a continuous film which moves outwards towards the orifice for droplet formation thereat. The supply of air and liquid to a chamber wall (42, 108) or target from which the liquid proceeds with direction change to an entrainment outlet at suitable pressures causes droplets formed to have a droplet size particularly suitable for effective coating of plant material and the momentum provided to the droplets by the air enables controlled direction of the resulting spray mist even at very low liquid volumes per hectare.
