格子ボルツマン法による2次元流路内流れの数値的研究 Numerical Study for Two Dimensional Channel Flow by Lattice Boltzmann Method 中西, 助次 ナカニシ, スケツグ 鈴村, 文寛 スズムラ, フミヒロ 山崎, 哲史 ヤマサキ, アキフミ Nakanishi, Suketsugu Suzumura, Fumihiro Yamasaki, Akifumi 501.23 Fluid Dynamics Numerical Solution Lattice Boltzmann Method Navier-Stokes Equation Channel Flow application/pdf It has been verified by many researchers that the lattice Boltzmann method has the ability to simulate the viscous fluid flow as precisely as the finite difference method. The incompressible viscous fluid flow in the inlet section of two-dimensional channel are computed by the lattice Boltzmann method. In this paper, the computed results by the lattice Boltzmann method are compared with the results using finite difference method, and are discussed for the concave velocity profiles at the initial stage of development channel flow. 広島工業大学 2004 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/665 AA11599110 13469975 広島工業大学紀要. 研究編 38 41 46 https://it-hiroshima.repo.nii.ac.jp/record/665/files/kenkyuhen38041.pdf application/pdf 341.0 kB 2023-03-30
