Two-Phase Newtonian-Rheological Flow

In Louisiana, underwater 3D concrete printing (3DCP) can support rapid post-disaster repair, ecological restoration, and protective coastal construction, yet the fundamental hydrodynamic mechanisms governing print stability are still poorly understood.

In this project, we will characterize two-phase flow interactions, where the fresh concrete and water are modeled as a Bingham fluid and a Newtonian fluid, respectively. The numerical module will be calibrated by rheological experiments, and then integrated into an open-source platform to extend its capability for simulating underwater 3DCP. The outcomes will establish safe operational conditions for underwater 3DCP, quantify relationships between rheological and environmental parameters, and deliver a computational tool for the assessment of buildability and structural integrity.
