Abstract
This study seeks to assess the performance of cold sprays of refined soybean oil produced by the Flow-Blurring (FB) atomization process. A cold diesel spray is also investigated for comparison. Drop size and velocity measurements for different fuels and operating conditions are acquired by a Phase Doppler Particle Analyzer (PDPA). Results show that the pressure drop in the fuel and atomizing airline of the FB injector is independent of the fuel. Radial profiles of Sauter Mean Diameter (SMD) were however affected by the fuel properties. For an Air to Liquid mass Ratio (ALR) of 2.0, the average SMD at an axial plane was about 38 μm for the VO sprays and 34 μm for the diesel spray. Increasing the ALR to 4.0 decreased the SMD in the VO spray to about 32 μm.
