Physical and analog interpretations of the mean energy flux balance are presented for the general case. A formal solution of the equation for mean flow of energy due to momentum fluctuations is presented, leading to a definition of local fluctuating dynamical equilibrium of a time-stationary flow ...

摘要: For a class of similarity solutions of the Navier-Stokes equations called general Slezkin flow, explicit expressions are derived for the components of the momentum-flux tensor. Remarkably enough some of the components depend only on the coefficients of the governing differential equation. Closel...
Linear mountain wave theory is used to derive the general formulas of the gravity wave momentum flux (WMF) and its vertical divergence that develop in directionally sheared flows with constant vertical shear. Height variations of the WMF and its vertical divergence are studied for a circular bell-...
It is a vector equation with three components. For steady transfer of momentum without generation, the conservation statement for momentum reduces to (8.1-1)(Rate of momentum in) − (Rate of momentum out) = 0 When there is no generation of momentum, it is implied ...
Magnetic flux is formally calculated as an integral, but the magnetic flux equation can also be calculated as the dot product of the magnitude of a magnetic field and an area, {eq}\Phi = |B|A cos(\theta) {/eq}, where {eq}\Phi {/eq} stands for the magnetic flux and {eq}\theta...
混合物动量方程 (Mixture momentum equation) 体积分数方程(Volume fraction equation) 相对速度 (drift velocity) 的封闭模型 漂移速度往往由经验公式或理论模型(这个漂移速度有很多模型,后续教大家了解一下of本身自带的漂移速度模型,咱们也可以自己写一个模型放进去)给出,例如: ...
The ANSYS FLUENT code was used to connect the energy and momentum equations. The SIMPLE methodology, or semi-implicit method, for the pressure dependent equations was used to solve the continuity equation. The solution of the energy equation is solved via second-order upwinding, and the resolutio...
new momentum equation,the potential energy of Rossby wave is derived and Lagrangian of nonlinear barotropic vorticity equation can be approximately found with this potential energy.This provides a physical basis for studying the dynamics of nonlinear Rossby wave with the approach of calculus of ...
This maximum point, furthermore, becomes identical to the point at which an envelope line generated from momentum equation and its partial derivative, intersects the mass balance line. The CHF calculated from the maximum liquid rate, is found to be in fairly good agreement with the existing CHF...
