Spraying Devices Design For Simulations of Aerosols And Air Interaction
Author:
Abstract: The current work aimed to study and understand the nature of interaction between aerosol/dusts and its surrounding medium such as air and/or solid dry or wet surfaces. Results were used as benchmarks to design spraying mechanisms and devices that can be used for optimizing the spraying device design geometry and shape with adjustable distance between cup and pin in parts and to lower manufacturing cost using solid works flow simulations software. Different spray devices were designed and evaluated with simulation, from simple ideas to complex device shapes. The simulation focused on studying the air profile and stream lines, with and without particles (dust particles with spherical shape and 5 micro meters in diameters), pressure, velocity and density during spraying process. Simulation results for the last modified spraying device case-6 with mass flow rate of 1.5 kg/s, and distance between cup and pin of ( part 2) 3.3 mm showed excellent mixing and spreading mechanisms with uniform velocity of flow, density and pressure through the whole device. Even the tested device in case-3 with mass flow rate 1 kg/s, distance between cup and pin of (part 2) 6.6 mm was also perfect. This device is expected to be used as a nanoparticle spraying device, a pollination device in date palm tree pollination and an aerosols aerodynamic behavior simulating system.
