Lattice Boltzmann simulation reveals supercritical bifurcation in flow mode transitions of power-law fluids in the four-roll mill
Yuan Yu, Xiao Jiang, Qingqing Gu +3
The four-roll mill has been traditionally viewed as a device generating simple extensional flow with a central stagnation point. Our systematic investigation using a two-relaxation…

Preferential imbibition in a dual-permeability pore network
Qingqing Gu, Haihu Liu, Lei Wu
A deep understanding of two-phase displacement in porous media with permeability contrast is essential for the design and optimisation of enhanced oil recovery processes. In this p…
