Description

Despite the low flow velocities characteristic of Microbial Induced Calcite Precipitation (MICP), laminar vortices can form in response to the dynamic alterations and complexity of the pore structure. These vortices significantly influence the mixing of bacteria and substrates, thereby affecting calcite precipitation. Gaining insights into the vortex impact on MICP within the pore space is crucial for advancing geotechnical applications, yet poses significant challenges for both experimental and numerical quantification. This study unveils our latest findings on laminar vortex dynamics within a 3D MICP numerical microfluidic model, an extension of our earlier 2D model. The enhanced 3D model enables a detailed quantitative analysis of vortex patterns and their correlation with the strength and distribution of vortices, as well as the mixing of substances.
