We propose a groove-embedded partitioned pipe mixer (GPPM) and conduct an in-depth numerical study on the flow and mixing characteristics of the GPPM in the creeping flow regime. The GPPM is a variant of a previously reported mixer, the barrier-embedded partitioned pipe mixer (BPPM), and is designed to achieve better energy-efficient mixing compared to the BPPM. In this paper, we first introduce the working principle of the GPPM and its mixing protocols. Then, the flow system affected by mixing protocols and geometrical parameters of the GPPM is investigated using Poincaré sections. As for mixing characteristics, the flux-weighted intensity of segregation is employed for quantitative mixing analysis. It turns out that a GPPM with a proper set of design parameters can indeed lead to a globally chaotic mixing. More importantly, the best GPPM showed better mixing in terms of energy consumption compared to its counterpart, the best BPPM.

我们提出了一种沟槽嵌入式分隔管混合器（GPPM），并对蠕变流态下GPPM的流动和混合特性进行了深入的数值研究。GPPM是先前报道的混合器的一种变体，它是壁垒式隔断式管道混合器（BPPM），与BPPM相比，其设计可实现更好的节能混合。在本文中，我们首先介绍GPPM的工作原理及其混合协议。然后，使用庞加莱截面研究了受GPPM混合方案和几何参数影响的流动系统。至于混合特性，采用磁通量加权的偏析强度进行定量混合分析。事实证明，具有适当设计参数集的GPPM确实可以导致全局混乱的混合。更重要的是，
