Characterization Of Rotary Bell Atomizers Through Image Analysis Techniques, Jacob E. Wilson
Characterization Of Rotary Bell Atomizers Through Image Analysis Techniques, Jacob E. Wilson
Theses and Dissertations--Mechanical Engineering
Three methods were developed to better understand and characterize the near-field dynamic processes of rotary bell atomization. The methods were developed with the goal of possible integration into industry to identify equipment changes through changes in the primary atomization of the bell. The first technique utilized high-speed imaging to capture qualitative ligament breakup and, in combination with a developed image processing technique and PIV software, was able to gain statistical size and velocity information about both ligaments and droplets in the image data. A second technique, using an Nd:YAG laser with an optical filter, was used to capture size statistics …
