Hydrodynamic energy

River Estuary, represented by B9, C7, C8, and C9 in the study area. Therefore, the sand concentrations of the stations mentioned above were higher than those of other stations. The finer sediments area in the SYS middle area reflected the effects of the transportation mode and sediments characteristics on the sediments t rpes. The clay sediments of the middle area in the SYS continental shelf tended to transport to the mid-north sediments area center, consistent with the cold vortex center by and large, located at about 123.5° E, 35.5° N. The weak hydrodynamic energy controlled by the cyclonic circum-fluence at the surface and cold vortex at the bottom resulted in the centrality of transportation (Shi et ah, 2002). Therefore, fine sediment particles were transported to the SYS middle area with the ocean current and settled down very tardily.

The viscous stress is related to the hydrodynamic energy dissipation W by (see Section 3.8.4)... 

The viscous stress is obtained from the hydrodynamic energy dissipation under a given velocity gradient. If we assume that the hydrodynamic interaction is completely screened, this is calculated in the same manner as in eqn (8.119) ... 

Pressure and stress. The stress or superficial force Fm is a scalar analogous to a pressure, but which is not endowed with aU its characteristics. It must be recalled that the pressure P is a state variable, an effort of the hydrodynamic energy variety, and that it is equal to a force divided by an area only in case of coupling with translation mechanics (see case study J5 Piston in Chapter 12). 

A pipe is a conductor of fluid, liquid, or gas, in the hydrodynamical energy. It has (always) two ends that are the two poles making up a conductive dipole. The pressure of the dipole is the difference between pole pressures. 

A piston is a system that couples hydrodynamic energy and mechanical energy of translation. 

Another acceptance of the notion of pressure is met with the local pressure, defined as the force density over a surface, which is a localized variable of the translational mechanical variety in contradistinction with the above-defined pressure which is a state variable in the hydrodynamical energy variety. 

The variation of the total capacitive energy is given by a Gibbs equation summing the variations of hydrodynamical energy and of physical chemical energy plus any other independent energy varieties (accounted for by a continuation mark ... ) ... 

The kinetic theory of gases is a classical model of relationship between the kinetic energy of the molecnles composing a gas and its hydrodynamical energy (volume energy). This model is based on the interaction between a wall and molecules colliding elastically with it (without dissipation). During a collision, a molecule exerts a force on the wall and this force is translated into a pressure within the container of the gas.
