Simulation of droplet impact dynamics on V-shaped walls

This paper presents the morphological evolution characteristics of a droplet impacting V-shaped wall by using lattice Boltzmann method (LBM). Four parameters are investigated comprehensively. The vary over wide ranges: surface wettability ( $$60^\circ \le \theta ^{eq} 120^\circ $$ ), Weber number $$102.27 \text {We} 3681.82$$ bending angle (90 $$^\circ 180^\circ and eccentricity ratio (0 $$\le b 0.5). Two types collision observed: deposition breakage. For breakage, satellite droplets increases against increment We. splashing occurs for high And lamella ejection is observed on hydrophilic neutral wall. will be slight increase $$\theta ^{eq}$$ , while it become obvious . In addition, nondimensional spreading length, width, height measured analyzed. Regime maps established based We, Re,
