Short abstract: What happens when the precision of agricultural spraying collides with the turbulence of a propeller wake? This study answers that question by investigating the impact of propeller wake on the spray geometry of standard ASABE agricultural nozzles.
Sensitivity Analysis of Event Based Algorithms for Velocimetry
Citation: 76. Khan, Abdul R., and Sidaard Gunasekaran. "Sensitivity Analysis of Event Based Algorithms for Velocimetry." In AIAA SCITECH 2026 Forum, p. 1316. 2026. https://doi.org/10.2514/6.2026-1316
Short abstract: Building on recent validation studies, the present work performs a systematic sensitivity analysis of a weighted event-based tracking algorithm applied to two configurations. The first is freestream and post stall flow around an SD7003 wing in a water tunnel.
Characterization of Rotary Atomizer Spray Geometry Under the Influence of a Propeller
Citation: 81. Grenwood, Brock A., Abdul Khan, Megan Bender, and Sidaard Gunasekaran. "Characterization of Rotary Atomizer Spray Geometry Under the Influence of a Propeller." In AIAA SCITECH 2026 Forum, p. 2700. 2026. https://doi.org/10.2514/6.2026-2700
Short abstract: Recent advancements in aerial spraying have driven a shift toward rotary atomizers on unmanned aerial vehicle platforms because they produce uniform droplet sizes at low flow rates with minimal clogging. However, the interaction between rotary atomizer plumes and UAV propeller wakes remains poorly understood.
