Efficient mixing conditions for similar fluids in T-Jets mixers are well-established. This paper extends the characterization of the mixing of dissimilar fluids. Planar laser-induced fluorescence images were captured using fluids with a viscosity ratio between 1.2 and 3. Flow visualizations showed that the best mixing conditions are achieved when the jets are well-balanced, and the onset of a chaotic flow regime is determined by the Reynolds number of the more viscous fluid (Re_Hjet > 100). Computational fluid dynamics simulations were also performed to get deeper insight into the flow field and mixing dynamics, enabling the prediction of the impingement point position. An analytical model based on jets' kinetic energy rate balance is proposed as a design tool to predict the impingement point position.

T-Jets 混合器中不同流体的流动方式和混合

T-Jets 混合器中类似流体的有效混合条件已经确立。本文扩展了不同流体混合的表征。使用粘度比在 1.2 和 3 之间的流体捕获平面激光诱导荧光图像。流动可视化表明，当射流平衡良好时，可以实现最佳混合条件，并且混沌流动状态的开始由雷诺决定较粘稠流体的数量（Re _Hjet> 100)。还进行了计算流体动力学模拟，以更深入地了解流场和混合动力学，从而能够预测冲击点位置。提出了一种基于射流动能率平衡的分析模型作为预测冲击点位置的设计工具。
