Abstract The aim of the present study is to optimize the micromixer with circular mixing chambers (M-CMC) using Taguchi-based grey relational analysis approach. Simulations are performed to investigate the effect of design parameters viz. chamber diameter, transverse offset and width of constriction channel on performance characteristics for parameter sets corresponding to Orthogonal Array (OA) L9. Further, grey relational grade is used to identify the optimal set of design parameters. In depth study of flow and mixing dynamics are carried out to visualize the mixing mechanism for optimal and other two cases of proposed micromixer design configuration for Re in the range from 0.1 to 50. In order to assess the response of each design variable at each level, analysis of variance (ANOVA) is also performed to analyse influence of design parameters on mixing index and pressure drop.

使用基于田口的灰色关联分析设计优化带有圆形混合室 (M-CMC) 的微混合器

摘要 本研究的目的是使用基于田口的灰色关联分析方法优化具有圆形混合室 (M-CMC) 的微混合器。进行模拟以研究设计参数的影响，即。腔室直径、横向偏移和收缩通道宽度对与正交阵列 (OA) L9 对应的参数集的性能特征。此外，灰色关联等级用于确定设计参数的最佳集合。对流动和混合动力学进行了深入研究，以可视化混合机制的最佳和其他两种建议微混合器设计配置在 0.1 到 50 范围内的 Re 的情况。 为了评估每个设计变量在每个级别的响应,
