equationsound velocityfunction of pressurereal gases/ A5140 Acoustical properties of gasesultrasonic relaxationThe velocity of sound in real gases is commonly expressed in terms of the density and the virial coefficients. However, an equation for the sound velocity given explicitly in terms of the ...
Well, this message shows that the run is diverging, namely in pressure correction equation (Sec. 25.4.3 Pressure-Velocity Coupling of Fluent Users Guide). It's hard to tell why this is happening without checking your case. Are you following some of the solution convergence steps mentioned in...
The discretized pressure–velocity coupling equation is solved via the SIMPLEC method; the nodal Green-Gauss method processes the gradient term; the central difference method and second-order upwind scheme discretize the diffusion and convection terms; and the discrete continuous equilibrium method in the...
We have found that velocity as a function of porosity, clay content, and effective pressure can be modeled as V = ao - a1φ a2Ca3e-a4 Pe. Where Pe is effective pressure in MPa. T his equation is in agreement with observed linear dependence of velocity on clay and porosity and non ...
Portal venous pressure refers to the pressure within the portal vein, typically ranging from 5 to 10 mm Hg, with a slight increase compared to the inferior vena cava or hepatic vein pressure. An elevation in portal pressure, often caused by conditions like cirrhosis, can lead to portal hyperte...
A new transport equation for the intermittency factor was proposed to predict separated and transitional boundary layers under low-pressure turbine airfoil... YB Suzen,PG Huang,LS Hultgren,... - 《Journal of Turbomachinery》 被引量: 148发表: 2003年 Burning velocity of turbulent premixed flames in...
This evolution equation shares similarities with earlier phenomenological models for the Lagrangian velocity gradient tensor evolution, yet constitutes the starting point for a systematic study of the unclosed pressure Hessian and viscous diffusion terms. Based on the assumption of incompressible Gaussian ...
Plastic crystals as barocaloric materials exhibit the large entropy change rivalling freon, however, the limited pressure-sensitivity and large hysteresis of phase transition hinder the colossal barocaloric effect accomplished reversibly at low pressure.
The anisotropy of elastic modulus, mechanical hardness, minimum thermal conductivity, acoustic velocity and thermal expansion of magnesite under high pressure are investigated using the first-principles calculations within the density functional theory. The calculated phase transition pressure, equation of stat...
The Bernoulli equation is arguably the most commonly used equation in fluid mechanics. For the incompressible, inviscid flow along a streamline, the Bernoulli equation states that the total head of the fluid (the sum of the pressure head, velocity head, and elevation head) is constant. Neglecting...
