We discretize the incompressible Navier–Stokes equations on a polytopal mesh by using mimetic reconstruction operators. The resulting method conserves discrete mass, momentum, and kinetic energy in the inviscid limit, and determines the vorticity such that the global vorticity is consistent with the ...
Results We generate a statistically stationary, homogeneous, isotropic flow of a dilute polymer solution by the DNS of the Navier-Stokes equations coupled to the evolution of polymers described by the Oldroyd-B model: ρf(∂tuα+uβ∂βuα)=−∂αp+∂β(2μfSαβ+μpτpCαβ)+...
90., 91. With regard to the EL approach, DNS of the continuous phase, that is, a full resolution of all length scales92 and the filtered Navier-Stokes equations93 have been reported. Particle-Based Systems Many pharmaceutical manufacturing operations, especially in secondary (drug product) ...
y,z) – these are the Navier-Stokes equations, and they conserve mass. Then there are also equations to conserve humidity and heat. There is an exact solution to the equations but there is a bit of a problem in practice.The Navier-Stokes equations in a rotating...
(Wu and Davidson1972; Vasyliunas and Siscoe1976). Multiple demonstrations of this are provided by the turbulence transport models and cascade rates computed on the basis of the MHD extensions of the Navier-Stokes theory. Shears, shocks, and coherent structures also play important roles, thus ...
The governing equations were the continuity and the Navier–Stokes equations for unsteady, laminar, incompressible flow, which are expressed as $$\frac{{\partial u_{i} }}{{\partial x_{i} }} = 0,$$ (1) $$\frac{{\partial u_{i} }}{\partial t} + u_{j} \frac{{\partial u_...

Unfortunately, while the motion of gases and liquids is generally known to follow Navier–Stokes equations, the motion of solids presents different characteristics depending on the type of system, solid concentration and interactions, showing solid-like behavior when a packed bed is subjected to quasi...
The viscous flow theory has gradually become the main method to study the bubble collapse dynamic behaviors due to its excellent performance of simulating viscosity effect and rebounded bubble shapes. Its main idea is to solve the Navier-Strokes (N-S) equation, as well as the two-phase flow ...
