The control volume approach in fluid mechanics relies upon the conservation of energy, momentum and angular momentum. However, open channel flows are typically related to only conservation of energy and momentum. Thus, for flows of non-uniform velocity and non-hydrostatic pressure distributions, the ...
(1994) extended Backus and Mulcahy’s treatment to include fluid-dynamical description with a mass advection term, and introduced a concept of inertial glut; they further gave a clear definition of single force (and torque) source as a momentum (and angular momentum) exchange between the seismic...
The Leading Edge Problem in Fluid Mechanics The self-similar momentum ordinary differential equation (MODE) and the self-similar partial differential equation (MPDE) have been derived and the investigation of the integrability of the MODE and the MPDE has been done by performing P... USN Bala...

We show that the law of consevation of angular momentum in a flow of an incompressible Stokes fluid can, in a particular case, be reduced to the equation of vortex diffusion. We perform the analysis using two different representations, the Euclerian and the Lagrangian, of the kinetic moment ...
The moment-of-momentum equation (VAM model) provides a means to calculate the additional integral velocity, u1. A 2D version of the new formula is also proposed and used to predict the direction of the near-bed velocity downstream of an oblique negative step. The agreement with the measured ...
Let the classical particle be, at the initial time t = 0, out of thermal equilibrium with the hb, and have a probability distribution Wc,in = Wc,in(x, q) (≥ 0) to be at the position x with momentum q. Then, the non-equilibrium particle could be, at time t(> 0), at the ...
In addition, the momentum transfer on the V-grid tray and its effect on clear liquid height and hydraulic gradient cross tray are discussed. 通过对塔板上气、液两相间的动量传递进行分析,讨论了动量传递对液面落差和清液层高度的影响。 3. With the dimentional analysis, the fluid momentum transfer ...
Some General Aspects Let a classical non-relativistic particle, with mass m, position x and momentum q, be subject to a real potential V = V (x), in the presence of a "heat bath" (hb) at thermal equilibrium at absolute temperature T , with β = (kBT )−1 (kB being Boltzmann's...
