Gasoline-Ethanol (Gasohol) Fuel Blend Spray Characterization using Digital Imaging and Image Processing

This paper tries to characterize the spray of gasoline ethanol blends using schlieren imaging technique and image processing. Five different gasoline-ethanol fuel blend rates by volume are prepared. The Image of the spray is captured using schlieren imaging technique and image processing is employed to extract macro spray characteristics- spray tip penetration and spray cone angle. Based on the extracted tip penetration and cone angles E55 gasoline-ethanol blend found out to have the largest cone angle and tip penetration among the tested blends.
