A momentum balance calculation in the longshore direction shows a surface level gradient of order 106 to be the proximate cause of the longshore flow. A very simple model of the observed phenomena is a sloping plane beach acted upon by cross-shore wind, varying sinusoidally in the longshore ...
The response of the surface mean wind vector to the synoptic pressure gradient was statistically calculated over the region of central Japan. The response was examined as related to the thermal effect, caused by daytime heating and nocturnal cooling in the surface layer. In the process of vector...
So, when an (elastic) polymer solution or melt flows along a pressure gradient, it is less compressed in the direction of flow than in the other two normal directions. The so-called First Normal Stress Difference N1 is defined as the total normal stress in the direction of the flow (σ...
A higher convergence results in a steeper pressure gradient. In addition, due to the turbulent nature of the flow, the pressure fluctuates; thus its instantaneous value may drop below the average pressure while the fluid may reach an early flashing inception. Hence, the fluctuating pressure may ...
A modification of the RANS turbulence model SSG/LRR- $$\omega $$ for turbulent boundary layers in an adverse pressure gradient is presented. The modificati

the prediction of the central pressure deficit by gradient wind balance has yet to be directly tested, nor has its implicit dependence on the nature of the low-level wind field been rigorously analyzed in pursuit of a simpler physical understanding that is both operationally accessible and consisten...
I'm working on the case when I have to simulating airflow over a wind turbine blade. The problem is to determine total lift and drag force occurred over the blade in rotation but instead of making rotating blade and solve transcendent case, I've decided to apply velocity ...
Parallel roller bearings can carry high radial loads but offer no resistance to forces in the axial direction, whereas radial ball bearings, although primarily intended to carry radial loads, can also support a smaller axial load. Many other designs of bearing are used, which provide for a wide...
1, the velocity profile in a turbulent boundary layer is strongly different from the laminar one in particular in the near wall region where the vertical velocity gradient, ∂U/∂y, is really more important giving rise to a high value of total pressure. All these sensors and their ...
