The turbulent flow in a square channel with weak curvature in which Re number was beyond 106 was investigated. The height of channel and the width are 5.5m and 4.8m, respectively. Numerical simulation by κ-ε model was also carried out. The calculated results except the turbulent kinetic ene...
The present paper explores the characteristics of turbulent flow and drag over two artificial 2-D forward-facing waveform structures with two different stoss side slopes of 50deg and 90deg, respectively. Both structures possessed a common slanted lee side slope of 6deg. Flume experiments were condu...
采用实验和数值模拟方法对安装在反应釜内壁侧的螺旋半圆管夹套中流体的湍流流动特性进行了研究. 无量纲曲率d=0.133、无量纲螺距t=0.127的夹套中流体湍流速度场的实测与模拟结果吻合较好. 基于正交螺旋坐标系,给出了夹套内流体的速度场,包括平均轴向速度、二次流速度及二次
In ocean environments, the flowing characteristics of turbulent flow are dominated by the additional force parallel to flowing direction. The effect of additional force perpendicular to flowing direction is very limited. In rolling and heaving motions, if the flowing velocity is the same, the flowing...

The experimental data were compared with traditional convective heat transfer and viscous pressure drop correlations for fully developed turbulent flow. It was found that if the measured thermal conductivities and viscosities of the nanofluids were used in calculating the Reynolds, Prandtl, and Nusselt ...
The flow of the cleaning wind is blocked by the grains, and therefore the distribution of wind velocity changes. It is found that the energy loss of the cleaning wind is not a result of turbulent flow. The wall friction and the pressure change observed as a result of the shape and the ...

The length of each foil, L, is 1, and the free-stream velocity, U, is 1. The Reynolds number of the simulation remains to be 400 for all the cases. This is because the current simulation method is mostly validated with laminar flow conditions [15] and turbulent flow is yet to be ...
