Abstract

application/pdf

We verify the accuracy of the interface capturing method in order to calculate the motion of a droplet on a hydrophobic surface by the immersed boundary-lattice Boltzmann method (IB-LBM). To exactly derive the Chan-Hilliard equation, we use the proper source term proposed by Liang and the two-relaxation-time (TRT) collision operator. The series of the numerical tests, including Zalesak’s disk rotation, a single vortex, and a deformation of a sphere demonstrate that the computational effectiveness of the TRT collision operator is superior to that of the multi relaxation time (MRT) collision operator. The present IB-LBM with the TRT collision operator appropriately calculates the contact angle of a droplet on the hydrophilic or hydrophobic plate in two and three dimensions.
