The Blockage Ratio Effect to The Spray Performances

Nozzle sprays are used in wide range of application. The nozzle application is depend on the spray characteristics, by which to suit particular This project studies effect air blockage ratio characteristics. research conducted into two part experimental and simulation section. was using particle image velocimetry (PIV) method, ANSYS software as tools for There nozzles were tested at 1 bar pressure water air. A (with 0.316) B (blockage 1.000). Both performances generated examined 9 cm vertical line from 8 orifice. validation result provided detailed analysis shows that trend graph velocity versus distance gives good agreement within experiment. From result, a wider angle higher droplet 31.41 degree 37.317 m/s compared has produced 27.13 penetration 16.49 velocity. As conclusion, affected system increasing inside system. happened condition pressure.
