A Swirl-Driven Grouting Control Method for Non-Newtonian Fluids: 2.5D Seepage Model and Stability Analysis of Fractal-like Viscous Fingering

In porous media grouting, highly viscous non-Newtonian fluids often trigger viscous fingering (Saffman–Taylor instability) due to adverse mobility ratios, creating fractal-like preferential channels that severely weaken the reinforcement volume. To overcome this, a novel swirl-dr...
