概要 |
Two-dimensional computational model for two-phase flow in a vertical cylindrical tank was derived and computed successfully. The height of a cylinder is 8cm and the diameter of a cylinder is 16cm. Air... was injected through a glass filter located at a bottom center of a water tank. Computational model is based on a dispersed model after Kataoka and Tomiyama. Effect of computational grid sizes and the boundary condition at a top surface of water are studied. Computed results are compared with flow visualized experimental results and confirmed that the rigid surface condition is better than free slip condition.続きを見る
