WitrynaMore details on the immersed boundary method can be found in [37] and the references therein. Typically, in the framework of the IB method, the elastic boundary is treated as a collection of elastic fibers. Alternatively, the elastic boundary is also modeled as an elastic membrane [11] or a thin shell [17]. These models are used to … WitrynaImmersed Boundary. 法による数値波動水槽の構築とその応用に関する研究―水平円柱周りの波浪場への適用―823 (13) (14) (3)数 値計算手法 基礎方程式をデカルト座標 …

WitrynaA combination of the lattice-Boltzmann and immersed-boundary methods is used to simulate the behaviour of circular particles in fluids, including their behaviour in stationary and flowing fluids. Thi WitrynaThe immersed boundary (IB) method was introduced to study flow patterns around heart valves and has evolved into a generally useful method for prob-lems of fluid{structure interaction. The IB method is both a mathematical formulation and a numerical scheme. The mathematical formulation em-ploys a mixture of Eulerian and …
