PropaneIn the present paper, a new equation for the dynamic viscosity of propane is presented, which is suitable for the application in mixture models. The dilute-gas contribution was adopted from Vogel and Herrmann (J Phys Chem Ref Data 45:043103, 2016). The residual part is an empirical ...
A gas of density ρ = 0.9487 kg/m3 and dynamic viscosityμ = 3.1 × 10−5Pa s flows through the bed with a superficial mass flow velocity of 1.4 kg/m2 s. Determine the pressure drop in the bed. Solution From Ergun's Eq. (4-4) (4-343)−dPdl=fρvs2gcDpwhere the friction ...
where μ is the dynamic viscosity of the fluid, K the permeability of the porous medium and CF the non-linear momentum loss coefficient. For low air speed values observed inside the canopy, the first term of Eq. (3) to the right can be neglected compared to the quadratic one. Combining...
mu = dynamic viscosity L = restriction length It is important to note that this equation is a general model for flow restrictors. An assumption that a sharp edged orifice is used. As the orifice changes, so does the design parameters on the equation. Additionally, flow will never be specifi...

A new dynamic one-equation subgrid-scale (SGS) model is presented for large eddy simulations of turbulent flows. The new model, combining both advantages of the dynamic one-equation SGS model (J. Appl. Mech. (ASME) 2006; 73:368-373) and the wall-adapting local eddy viscosity model (Turb...
where ∇P is the fluid pressure gradient, g is the gravitational acceleration, ∇z is the gradient in the vertical direction, μ is the dynamic viscosity, and k is the permeability tensor. 2.3.2 Multi-phase flow Typically, the voids of the geological formation in which CO2 is injected ...
The Jacobians are evaluated using either the left or the right state for all variables except for the dynamic viscosity, which is determined from an arithmetic average. It should be mentioned that Eq. (6.45) leads to a second-order central difference approximation in the implicit operator, ...
