Limitations of the Navier–Stokes equations for some problems are mentioned and a more detailed analysis of this point for the shock wave problem is considered.doi:10.1142/9789812811592_0027F.J. UribeUribe, F. J.: Understanding dilute gases: Going beyond the Navier–Stokes equations. In: ...
Firstly, the PISO algorithm is used to solve the incompressible Navier-Stokes equation for the whole CFD domain with the presence of the particles being excluded:(1)ρu¯−un−1∆t+ρun−1·∇un−1=−∇p¯+μ∇2un−1(2)∇·u¯=0 In IBM, particles interact with...

We performed Computational Fluid Dynamics (CFD) simulations using COMSOL Multiphysics® v.5.5, where the Cahn–Hilliard phase-field method was coupled with Navier–Stokes equation49,50,51. As a result, we obtained the velocity and pressure fields and the medium’s distribution of the phases. ...
refer to the convective velocity vector and thediffusion coefficient, respectively, while represents an arbitrary source term. This equation could represent the energy equation, i.e., the heat transfer equation, mass transport equations (used for the transport of chemical species),Navier-Stokes equatio...
s sine-squared law is that fluid cannot be simply treated as a collection of individual non-interacting solid particles. Newton’s second law should be applied to fluid as a continuum, which leads to the momentum equation in fluid mechanics, i.e., the Navier-Stokes equations (the NS ...
(Lovejoy2015). The view is inspired by turbulence theory, in which scale analysis of the governing Navier–Stokes equations provides a constraint on the slope of the expected spectrum (Lovejoy and Schertzer2013). Similar scale invariance has recently been detected in a low-order ice-sheet ...
It is possible to computationally solve the Navier-Stokes equations in the case of high Reynolds number of aerodynamics, using a slip boundary condition as a model of a turbulent boundary layer with small skin friction. It is possible to theoretically understand high Reynolds number bluff body flow...
I understand that CFD solves Navier Stokes Equation but sometimes I am confusing about those kinetic/turbulence terms. I did took up Turbulence topic and understand that dissipation of energy etc. But there are so many things going around now and I am kind of (So) lost. :confused: ...
In this work, we analyse the influence of the parameters of a mathematical model, previously proposed by the authors, for reproducing atheroma plaque in arteries. The model uses Navier–Stokes equations to calculate the blood flow along the lumen in a tr
