External mix air atomising nozzles

In standard air atomising nozzle the mixing of the gas and fluid occurs internally prior to exit from the spray orifice.  For fluids with a viscosity above 200CP this mixing internally will result in poor spraying as the viscous fluid will not move well through the spray orifice.  A solution to this problem is to widen the spray orifice and to impinge the atomising gas onto the fluid after it has exited the orifice (illustrated below)
