This study presents a groundbreaking conceptual innovation of a fan-shaped twin-fluid injector meticulously conceptualized and developed. A thorough performance assessment of the injector is being executed, employing water and compressed air as working substances. Measurements of droplet size and velocity are being carried out through the phase Doppler particle analyzer system, encompassing heightened feed flow rates and a range of airflow conditions. Moreover, an exhaustive exploration of spray spread dynamics is underway across three distinct impactor positions using high-speed imaging. Notably, at a moderate air-to-liquid ratio, the radial expansion of the spray is conspicuously intensified at the central impactor bolt position, surpassing the expansion at other positions. This phenomenon can be attributed to heightened turbulence levels resulting from the central impactor's presence, intricately shaping the resulting spray dispersion patterns. Another key insight is the substantial influence of droplet size and velocity distribution within the spray, driven by increased spray instability due to the presence of the impactor bolt.
