Calculated turbulent energy in the relaminarization shows exponential decay for 600 ≤ Re ≤ 1230, where Re is the Reynolds number based on the streamwise velocity at the centerline and the half width of the channel. Also, a halflifetime of turbulence is calculated. The inverse of the half-lifetime decreases exponentially up to Re ≈ 1000 and over the value it gradually approaches zero. The present results indicate that process of relaminarization in plane Poiseuille flow can have similarity to that in pipe flow investigated by previous research work., Article, 計算数理工学論文集. 7(2):255-260 (2008)}, pages = {255--260}, title = {Lattice Kinetic スキームを用いた二次元チャンネル乱流の再層流化現象の解析}, volume = {7}, year = {2008} }
