Mixing Characteristics of Non-Newtonian Impinging Jets at Elevated Pressures

Binary collision of CMAS droplets—Part I: Equal-sized droplets

“…Further, the code is parallelized based on message passing interface libraries for massively parallel computations. This framework has been used extensively for a wide range of multiphase flow problems, including liquid jet atomization in the presence of broadband inlet fluctuations, impinging liquid jets, droplet breakup, and collision phenomena [29,49,50,51].…”

Binary collision of CMAS droplets—Part II: Unequal-sized droplets

“…As specified in the previous study, the viscosity and surface tension of CMAS are at least two orders of magnitude higher than that of the liquids investigated in the literature; their dynamic behaviors are expected to be significantly different as compared with low viscosity fluids. This hypothesis is based on our previous experience on the dynamics and atomization physics of highly viscous and non-Newtonain fluids [23,24,25,26]. Furthermore, to the best of our knowledge, there are no studies detailing the mechanistic behaviors of off-center and grazing type collisions for unequal droplets, which alongside head-on collisions are equally possible in the hot gas path of a gas-turbine engine.…”
