The present study considers computational evaluation of mixing performance in a T‐mixer having staggered fins. A novel arrangement consisting of two pairs of staggered fins is incorporated and placed close to the entrance of the mixing channel. A parametric study is performed to examine the effects arising from the geometric and flow parameters alteration. With respect to all the parameters investigated, the presence of staggered fins consistently give rise to better mixing performance as compared with that without fin. With the presence of fins, flow of liquid with different species concentrations is redirected and aligned with the angle of inclination θ of the fins, creating lateral convection that disrupt the flow. This promotes better mixing of liquids. At Re = 1, staggered fins arrangement with θ = 45°, enhancement in mixing efficiency can reach as high as 33.3% as compared with that of without fin. It is also interesting to note that liquid mixing enhancement is significant at higher Reynolds numbers (1 ≤ Re ≤ 10) as compared with that of low Reynolds value (Re < 1).

翅片交错的T型混合器中增强的液体混合

本研究考虑了具有交错鳍片的T型混合器中混合性能的计算评估。一种新颖的装置包括两对交错的鳍片,并放置在靠近混合通道入口处。进行参数研究以检查几何和流量参数更改产生的影响。关于所研究的所有参数,与没有翅片的翅片相比,交错翅片的存在始终带来更好的混合性能。由于存在翅片,具有不同种类浓度的液体的流动被重定向并与翅片的倾斜角θ对准,从而产生横向对流,从而扰乱了流动。这促进了液体的更好混合。在Re = 1θ = 45°的交错翅片排列方式,与没有翅片的混合效率相比,混合效率提高了33.3%。这也是有趣的是,液体的混合增强是显著在较高的雷诺数(1≤重新≤10)作为与低雷诺数值的比较<1 )。
