Abstract

This study investigates the effect of system softness on Haines jumps and drainage in porous media using microfluidics. A gas bubble with controlled volume is introduced into the liquid phase to create a soft system. A pore-scale analytical model incorporating softness is developed, and a dimensionless number is proposed to characterize it. Experiments in single pore throats, pores-in-series, and pore networks show that increased softness leads to longer jump distances and waiting times. In series pores, system softness determines the number of pores filled during a jump, while in networks, softness alters invasion dynamics but not the final saturation pattern.
