AB - <p style="text-align: justify;">In the current study, a two-dimensional multi-relaxation time (MRT) lattice
Boltzmann model which can tolerate high density ratios and low viscosity is employed
to simulate the liquid droplet impact onto a curved target. The temporal variation of
the film thickness at the north pole of the target surface is investigated. Three different
temporal phases of the dynamics behavior, namely, the initial drop deformation phase,
the inertia dominated phase and the viscosity dominated phase are reproduced and
studied. The effect of the Reynolds number, Weber number and Galilei number on the
film flow dynamics is investigated. In addition, the dynamic behavior of the droplet
impact onto the side of the curved target is shown, and the effect of the contact angle,
the Reynolds number and the Weber number are investigated.</p>
