摘要：

We performed two-dimensional simulations of the slicing of a rising droplet by a vertical knife and by two knives. We used a free-energy lattice Boltzmann method. Most simulations are for an Eotvos number of 3.96 and a Morton number of 1.24 x 10(-4). We carefully probed effects of the spatial resolution on the rising speed and slicing process. The effect of wettability of the knife(s) was studied by varying the equilibrium contact angle of the drop on the knife in the range of 45 degrees to 135 degrees. Slicing time as well as fine droplet fragments staying behind on the knife depend on the knife's wettability.
