“…Authors attribute this pattern to reasons similar to those that promote it for non-reactive penetrations [22], considering how lift-off length is reasonably well correlated with jet penetration [34] and the coefficient trends of these injectors visible in [26]. Dodecane, being less viscous, must develop a higher Reynolds number and velocity [35]. In a cavitating regime as the induced by the Spray C nozzle, this high Re will increment the turbulence through the nozzle and the cavitation, enhancing the jet break-up, enlarging the spray angle and dropping the coefficient of area, or the effective diameter [36,37].…”

“…Although combustion performance is out of the scope of this publication, different fuels will present different behaviors regarding nozzle flow characteristics. Som et al [36] presented a study of the effects of fuel properties on cavitation characteristics and nozzle-outlet turbulence kinetic energy, similar to the experimental micro-visualization work presented by Payri et al [37] and later Jiang et al [38]. However, neither of these studies show the influences that different cavitation regimes found for each fuel may have on spray formation.…”

“…In order to observe the atomization mechanism of the Y-Jet atomizer shown in Fig. 3, it is necessary to use a visualization mechanism inside it [70,71]; thence, for the first prototype, an atomizer was built in polymethyl methacrylate (PMMA); unfortunately, this material reacted with TPO due to the presence of aromatic compounds [72]. Therefore, the PMMA injector was tested only with water where the adherence of liquid on the walls of the mixing chamber was observed, which revealed a high concentration of liquid forming a layer on its walls according to the mechanism shown in Fig.…”
