成果简介	NOVELTY - The nozzle (200) has a liquid outlet (102) for impinging a jet of liquid on a surface disk (104) to radially splash the liquid outward for forming a thin film of the liquid. A circumferential air nozzle (110) is provided with a cavity (112) to form an air jet that impinges a thin film of the liquid to form liquid droplets. The surface disk is positioned in a flow path of the liquid ejected from the liquid outlet. A side arm (116) is configured to hold the surface disk. The surface disk facilitates interaction between the air jet and the thin film of the liquid in cross-flow manner. USE - TFCF nozzle for an unmanned aerial vehicle (claimed) for spraying agrochemicals for crop. ADVANTAGE - The nozzle minimizes chemical wastage, reduces environmental impact and optimizes crop protection leading to increased agricultural sustainability and productivity. The nozzle provides a simple mechanism to control film thickness, enables adjustment to achieve minimum film thickness for different fluids, generates downward droplet-laden flow without using rotor downwash, improves droplet penetration during spraying operations and minimizes drift when locating close to an intended spraying area, thus enhancing accuracy of spraying process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an unmanned aerial vehicle. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a TFCF nozzle for an unmanned aerial vehicle for spraying agrochemicals for crop. 102Liquid outlet 104Surface disk 110Circumferential air nozzle 112Cavity 116Side arm 200TFCF nozzle
