| Outline of Final Research Achievements |
By combining the two-phase system Boltzmann method (two-phase system LBM) and the immersed boundary-lattice Boltzmann method (IB-LBM), we newly developed the three-phase LBM with good parallel computational efficiency and implemented it on the framework of an orthogonal lattice stacking method (Building Cube Method, BCM), which is one of the interface-adaptive lattice methods. This method can compute the complex deformation of the gas-liquid interface and the motion of a complex shaped object using the interface-adaptive grid, and it is a complete explicit method without the need to solve the Poisson's equation for pressure as in the conventional method. Therefore, it is a numerical computational method suitable for large-scale parallel computers.
