Hydrodynamics of a droplet passing through a microfluidic T-junction

Abstract: We develop a phase-field multiphase lattice Boltzmann model to systematically investigate the dynamic behaviour of a droplet passing through a microfluidic T-junction, especially focusing on the non-breakup of the droplet. Detailed information on the breakup and non-breakup is presented, together with the quantitative evolutions of driving and resistance forces as well as the droplet deformation characteristics involved. Through comparisons between cases of non-breakup and breakup, we find that the appearance … Show more

“…It is generally accepted that fractal geometry has the intrinsic advantages of minimized flow resistance [22,23] and strong heat transfer capability [24,25]. Therefore, there has been successful application of a fractal structure to the design of highly efficient heat exchangers [26,27], chemical reactors [28], heat sinks [29,30], and fluid distributors [31][32][33]. It was proven that fractal geometry can achieve a significant increase in the heat transfer area and flow access, with the increase in the fractal levels [34,35].…”

“…They have highly-efficient heat and mass transfer properties. At present, the dendritic structure has been widely used in optimizing the design of the channel structure in heat exchangers [23,24], chemical reactors [25], fuel cells [26,27] and microfluidic systems [28,29]. Moreover, the disc-shaped heat exchangers of dendritic structure, as a kind of point-to-area heat transfer structure, has been proved to be able to make even heat flow distribution and hence improve heat transfer performance as compared with traditional fin heat exchangers [30].…”
