2018年10月1日 · Contact angle, which indicates the interactions between solid surface and nonideal fluid, becomes particularly important in these researches. In this paper, we design a geometry-based mesoscopic scheme to measure the contact angle basing on the regular and discrete lattice of the lattice Boltzmann method.

Contact angle: The contact angle in the control file must be less or equal to 90 degrees due to the particular numerical scheme used, meaning that fluid1 and fluid2 will always be the nonwetting phase and wetting phase, respectively. Drainage and imbibition can be completed by injecting fluid1 and fluid2 respectively.

2015年9月11日 · In this work, a multiphase lattice Boltzmann method (LBM) is developed to simulate the contact-line dynamics with consideration of the contact angle hysteresis for a broad range of kinematic viscosity ratios.
