6) hydrostatic equation 流体静力学方程 例句>> 补充资料:流体力学的能量方程 是在密度均匀情况下反映机械能守恒的方程;在考虑密度、温度、内能变化时,反映包含内能的能量守恒定律(见热力学第一定律)的方程。根据所考虑的因素多少,流体力学的能量方程具有不同的形式。对于流场中一切量都是光滑函数的情况,它可列成...
This work intends to provide a review of details needed in modeling as Reynolds-averaged Navier–Stokes (RANS), large eddy simulation (LES) or Detached eddy simulation (DES) energy equation in CFD codes used for solving chemically reacting turbulent flows. When the...
Energy equations in OpenFoam #1 Bloerb Senior Member Join Date: Sep 2013 Posts: 353 Rep Power: 21 I am currently trying to better understand the energy equations used in OpenFoam solvers. http://cfd.direct/openfoam/energy-equation/ seems like a good start if you want to look at ...
However, there are major physical differences regarding the underlying mechanisms in the two types of media. In a porous medium, the obstacles are impermeable solid structures, while the fluid motion is governed by the Navier-Stokes equation in flat space. In a curved medium, however, the back...
Time-dependent quantum-fluid density-functional study of high-energy proton-helium collisions A quantum-fluid density-functional theory (QF DFT) is proposed, yielding a time-dependent (TD) generalized nonlinear Schroedinger equation (GNLSE) as the e... BM Deb,PK Chattaraj,S Mishra - 《Physical...
It is also shown that the initial discontinuity is significant to the energy dissipation which is non-trivial to simulate in 1-dimensional bubble dynamics equations like the Gilmore equation. Then, the relationship between dissipated energy and bubble maximum radii in adjacent pulsating cycles is ...
In the context of an interacting dark energy scenario the conservation equation can be separated into the following equations: ρb′+3ρb=0, (1) ρr′+4ρr=0, (2) ρc′+3ρc=−3Γ, (3) ρx′=3Γ, (4) where by convenience we use η=lna as time variable and we...
Fluid Dynamics: Fluid dynamics studies how fluids (liquids and gases) flow and interact with their surroundings. The kinetic energy equation is used to analyze the movement of fluids, predict flow rates, and determine the energy losses and changes in pressure during fluid flow. Astronomy and Astro...
Stability and the equation of state We examine the stability of equilibrium states by considering the Hessian of the total energy Utot, given by Hij = ∂2Utot/∂vi∂vj. An equilibrium configuration is stable if it corresponds to a local minimum of the energy, requiring positive defin...
While the dose deposition of charged hadrons has received much attention over the last decades starting in 1930 with the publication of the Bethe equation, there are still practical obstacles in implementing it in fields like radiotherapy and isotope production on cyclotrons. This is especially true...
