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.

Academic Significance and Societal Importance of the Research Achievements

本研究は,直交格子積み上げ法(BCM)のフレームワーク上に3相系LBMを実装するものある.本計算スキームは,界面適合格子上で完全陽的に計算を行う究極の局所的な計算スキームであり,並列計算機に最適な移動境界流れの新しい計算スキームである.研究代表者はこれまでに2相系LBMおよびIB-LBMの研究で世界を牽引してきており,本研究成果はさらに国内外の研究者に大きなインパクトを与えるものである.
