The sagion aether is described by the standard four-dimensional equation of fluids, and thus obeys the two basic laws of physics: conservation of linear momentum and conservation of total energy. All forces of Nature arise from local imbalances of pressure in the sagionic fluid, imbalances ...
Momentum Equation In subject area: Computer Science The Momentum Equation refers to the conservation law that describes how the variation of momentum within a control volume is influenced by external and surface forces acting on a fluid element.

Chapter 10 Momentum equation 10.1 Classification of the law of momentum The law of momentum was derived in Chapter 5 by means of integration of the Cauchy equation of motion over a control volume (see Figure 5.9). The internal forces that act upon the control volume are in equilibrium with ...
In the derivation of the momentum transport equation in Kirkwood's paper (https://aip.scitation.org/doi/10.1063/1.1747782), I am stuck at a particular point in the derivation. The rate of change of the expectation value of a dynamical quantity is derived (using Liouville's theorem and the ...

Thus, we have by Newton's second law per unit volume of fluid in the ithith direction, ρai=fi+∑j∂σji∂xjρai=fi+∑j∂σji∂xj And so the total force (all of the previous equation multiplied by the volume of the unit of fluid which it pertained to) is given as ρa...

These momentum equations are solved together with the continuity equation using a PISO loop (see, for instance, the comment by Hrv that follows http://www.cfd-online.com/OpenFOAM_D...html#POST17984 or references in the Wiki cited above). Therefore, the Implicitly Discretized Fluid Flow Equat...
