In this model, the momentum equations are transformed to wave-number space and re-normalization group theory is used to derive the equations for calculating eddy viscosity. Because the resulting equations have a firmer theoretical foundation, the results using the RNG model are usually more accurate...
momentum distributionrecoil generationThe Boltzmann transport equation is used to predict ion implantation profiles at low implantation energies, with particular attention to the effects of ions which are backscattered. In previous work the transport equation was applied stepwise into the target and all ...
7.4.2 Momentum Balance Equation (Equation of Motion) Considering the possibility of the inertial flow effects due to the narrowing of pores by formation damage, the Forchheimer (1901) equation is used for the momentum balance. Although more elaborate forms of the macroscopic equation of motion are...
It is shown that these methods can be derived from the drift kinetic equation with the same collision model used for correctly taking account of collisional momentum conservation. In both methods, the Laguerre polynomials of the energy variable are employed to expand the guiding-center distribution ...
For example, if v2 is greater than v1 in the equation, then P2 must be less than P1 for the equality to hold. Example 1. Calculating Pressure: Pressure Drops as a Fluid Speeds Up In Example 1 from Flow Rate and Its Relation to Velocity, we found that the speed of water in a hose...

If an object is moving at a constant velocity, we can compute it by calculating $$\vec{ v } = \frac{ \vec{ x_f } - \vec{ x_i } } {t_f - t_i} $$ Both the position {eq}\vec{ x } {/eq} and the velocity {eq}\vec{ v } {/eq} are vectors, that is, quantities ...
The fully off-shell LS equation for the T matrix is illustrated in figure 1. The corresponding integral equation in momentum space is given by T (p, q; q02 + iε) = V (p, q) + d3k (2π)3 V (p, k)T (k, q; q02 + iε) k2 − q02 − iε , where the explicit ...
There are three main methods used for calculating option values: partial differential equations, simulation, and lattice methods (Mun, 2006b), which we introduce below. 3.2.1 Partial differential equations Partial differential equations are a continuous time, analytical, mathematical approach to valuing...
