Characteristics of the boundary layer structure of sea fog on the coast of southern China. Adv Atmos Sci, 28(6): 1377--1389Huang, H. J., H. N. Liu, W. M. Jiang, et al., 2011: Char- acteristics of the boundary layer structure of sea fog on the coast of southern China. Adv...
The disturbances observed in the boundary layer were greatest at a turbulence on the order of 4.5%. It is noted that the longitudinal scale of turbulence increases monotonically toward the external side of the boundary layer, while the spectral distribution is characterized by low frequencies (up ...
Another interesting effect due to the shear is the appearance near the edge of the layer of a small but distinct region where the local mean velocity is constant and the Reynolds shear stress is negligible. 展开 关键词: Flow Velocity Shear Flow Turbulent Boundary Layer Turbulent Flow Uniform ...
The break-up of a field of eddies by a flat-plate obstacle embedded in a boundary layer is studied using numerical solutions to the two-dimensional Navier-Stokes equations. The flow is taken to be incompressible and unsteady. The flow field is initiated from rest. A train of eddies of pred...
Measurements of the flow velocity and suspended sediment profiles through one tidal cycle were taken from an observation platform in the Outer Thames Estuary at Maplin Sands. The flow velocity profile during the experiment was characteristic of an oscillatory boundary layer with the height of the bott...
The early-evening boundary layer transition has been defined in the past using a variety of criteria, the most popular of which is the onset of a negative surface heat flux. According to this definition, the transition is an almost-instantaneous event that occurs when the positive daytime heat...

In conclusion, boundary-layer bleeding can improve the performance parameter of hypersonic inlets, and can reduce the starting and restarting Mach number, and can broad the operation range of the hypersonic inlet. 展开 关键词: A_b area of the bleeding shown in Fig. 13 A_0 area shown in ...
In the case of transition/turbulent interaction, boundary layer transition comes to an end quickly downstream separation, then turbulence boundary layer and separation bubble dominate the interaction region, which makes the pressure and heat transfer distribution be similar with pure turbulent interaction ...
