An Elastic Analog Model for Controlling the Impingement Point Position in Confi...
Claúdio P. Fonte; M. Ashar Sultan; Ricardo J. Santos; Madalena M. Dias; José Carlos B. LopesConfined impinging jets (CIJs) are highly efficient mixers. The scales of mixing in CIJs are controlled by the opposed jets interaction. A mechanistic model is described here, which accurately predicts the impinging position of the opposed jets for a large range of flow rate ratios. The impinging point position is shown to impact the dynamic properties of the flow and the achieved mixing quality. The opposed je...
Flow imbalance and Reynolds number impact on mixing in Confined Impinging Jets
Cláudio P. Fonte; M. Ashar Sultan; Ricardo J. Santos; Madalena M. Dias; Jose Carlos B. LopesThe flow in a Confined Impinging Jets (CIJs) mixer was studied with Planar Laser Induced Fluorescence. Two key aspects influencing the flow regimes and mixing quality were studied: the impact of the jets' Reynolds number (Re) in the range 50 < Re < 600; and the effect of the jets' flow imbalance, maintaining the flow rate of one of the injectors fixed and varying the other. Mixing mechanisms and scales are stud...
