             abstract = "This work presents an experimental study on spray formation by 
                         unlike impingement of gelled ethanol with liquid water and liquid 
                         ethanol, and a comparison with spray formation by like impingement 
                         of gelled ethanol. High-speed shadowgraphy was utilized to analyze 
                         collision sheets, instabilities, breakup lengths and particles of 
                         sprays formed by colliding jets with 0.80 mm diameter with equal 
                         momentum and different collision angles and flow conditions. For 
                         unlike jet impingement, the sheet evolution and disintegration 
                         showed a mixture of patterns found in Newtonian and non-Newtonian 
                         fluids, such as complex structures with rails, holes, fishbone, 
                         detaching beads and ligaments. Regime transition for unlike 
                         impingement configurations is faster than for like impingement, 
                         consequently the breakup lengths for unlike impingement were 
                         significantly shorter than for like impingement. In general, the 
                         breakup lengths decreased for larger We or larger jet momentum 
                         values and increased for lower impingement angles. Despite the 
                         improvement in the atomization caused by unlike configurations, 
                         small ligaments remained in all sprays formed by unlike jets. The 
                         particle sizes and geometries for the different configurations 
                         were evaluated and compared in terms of circularity, percent area 
                         and Feret diameter. No significant differences of the spray 
                         regions were observed between the two unlike impingement 
                         settings.",
