Abstract:In order to clarify the flow characteristics of liquid on the surface,the fluid spreading process on solid surface was simulated numerically based on lattice Boltzmann molecular dynamics and level set interface tracking method.LBM was employed to solve the flow field of fluid motion,and the interface of solid-liquid-gas was captured by LS method.The obtained simulation results are in good agreement with the experimental measurement results.The spreading contact angle changes exponentially with time,and the contact angle reduces with the decreasing of fluid surface tension.It is certifiyed that LBM-LS model proves feasible to simulate the wetting problem.
