Convective mixing of two miscible liquids injected into a rotor-stator spinning disk reactor (RS-SDR) has been studied using an LIF technique and CFD simulations. The fluids are ammonia water and fluorescein ammonia water solutions. The RS-SDR has a rotor 100 mm in diameter and a thin circular cavity 0.10–0.15 mm in height between the rotor and stator. Laminar flow conditions for rotation speeds up to 120 rpm and total flow rates up to 8 mL/min are considered. The fluorescein solution is injected from the second off-center hole into the cavity filled with the ammonia water supplied from the central hole. The LIF technique visualizes a spiral streak pattern formed downstream of the second injection hole. This streak pattern is analyzed to calculate the local mixedness of the two fluids. It is determined that the mixedness increases for lower flow rates, while it is less sensitive to rotation speed and cavity height. The CFD simulations indicate that the spiral streak pattern is deformed and stretched in the radial direction to form a densely layered structure of the two fluids. The development of the mixedness along the streak pattern is correlated well with ${\mathit{Re}}_{\mathit{inlet}}/{\mathit{Re}}_{\mathit{cavity}}$, where ${\mathit{Re}}_{\mathit{inlet}}$ and ${\mathit{Re}}_{\mathit{cavity}}$ are the Reynolds numbers for the injected flow and the azimuthal flow in the cavity, respectively. This Reynolds number ratio is shown to be related to the Rossby number and the position and radius of the second injection hole. The proposed correlation is based on a linear combination of injection mixing and rotation mixing. The mixedness decreases with ${\mathit{Re}}_{\mathit{inlet}}/{\mathit{Re}}_{\mathit{cavity}}$ because the injection mixing decreases with ${\mathit{Re}}_{\mathit{inlet}}$ while the rotation mixing increases with ${\mathit{Re}}_{\mathit{cavity}}$.

已经使用LIF技术和CFD模拟研究了注入转子-定子旋转盘式反应器（RS-SDR）中的两种可混溶液体的对流混合。流体是氨水和荧光素氨水溶液。RS-SDR的转子直径为100 mm，转子和定子之间的高度为0.10-0.15 mm的薄圆形腔。考虑了层流条件，转速高达120 rpm，总流速高达8 mL / min。荧光素溶液从第二偏心孔注入到填充有从中心孔供应的氨水的腔中。LIF技术可视化形成在第二注入孔下游的螺旋条纹图案。分析该条纹图案以计算两种流体的局部混合度。已经确定，对于较低的流速，混合度增加，而对转速和腔体高度不那么敏感。CFD模拟表明，螺旋条纹图案在径向方向上发生了变形和拉伸，从而形成了两种流体的致密分层结构。沿着条纹图案的混合性的发展与${\mathit{关于}}_{\mathit{进口}}/{\mathit{关于}}_{\mathit{腔}}$， 在哪里 ${\mathit{关于}}_{\mathit{进口}}$ 和 ${\mathit{关于}}_{\mathit{腔}}$分别是腔中注入流和方位流的雷诺数。该雷诺数比显示为与罗斯比数以及第二注入孔的位置和半径有关。所提出的相关性基于注射混合和旋转混合的线性组合。混合度随${\mathit{关于}}_{\mathit{进口}}/{\mathit{关于}}_{\mathit{腔}}$ 因为注射混合会随着 ${\mathit{关于}}_{\mathit{进口}}$ 而旋转混合随着 ${\mathit{关于}}_{\mathit{腔}}$。
