对两种半径比(R1/R2=0.1和0.5)下Re Dh=890 0的同心环管湍流流动进行了直接数值模拟。重点研究了横曲率对近壁湍流结构的影响。通过计算各种湍流统计量,仔细研究了靠近内壁和外壁的近壁湍流结构。
A direct numerical simulation is performed for a turbulent concentric annular pipe flow at Re D h= 8900 for two radius ratios (R 1/R 2= 0.1 and 0.5). The main emphasis is placed on the transverse curvature effect on near-wall turbulent structures. Near-wall turbulent structures close to the inner and outer walls are scrutinized by computing various turbulent statistics.
