摘要
Labyrinthine instabilities of miscible magnetic fluids are simulated numerically. Great similarities of fingering patterns with the effects of interfacial-tension-like Korteweg stresses to their immiscible equivalents are found. A miscible magnetic Bond number is proposed so that the miscible studies might be able to link to immiscible cases. More vigorous fingerings are observed at stronger viscosity contrast as well.
