The Double-Logarithmic Regularity Criterion of Pressure for the 3D Navier–Stokes Equations in the Besov Space

Journal of Mathematics
In the paper, we consider the regularity of the weak solutions for the incompressible 3D Navier–Stokes (N–S) equations. Our main result is the double-logarithmic regularity criterion of pressure for the 3D Navier–Stokes equations in the Besov space ...

Characterization of Proppant Flowback in Hydraulic Fracturing Rough Fractures

Energy Science &Engineering, EarlyView.
This graphical abstract reveals the proppant flowback mechanism and controlling factors in rough fracture through CFD‐DEM modeling. This study investigates unavoidable proppant flowback during fracturing, which leads to wellbore sand plugging and reduced fracture conductivity. A coupled CFD‐DEM model simulates flowback in rough fracture, revealing that

A condition for the finite time blow up of the incompressible Navier–Stokes equations in the whole space

Results in Applied Mathematics
This paper is interested in the existence of singularities for solutions of the Navier–Stokes equations in the whole space. We demonstrate the existence of initial data that leads to the unboundedness of the corresponding strong solution within a finite ...

Optimizing a Straight‐Bladed Vertical Axis Wind Turbine With Computational Fluid Dynamics (CFD), Artificial Neural Network (ANN), and Genetic Algorithm (GA)

Energy Science &Engineering, EarlyView.
ABSTRACT Vertical axis wind turbine (VAWT) is a suitable renewable power generation tool for use in urban areas, especially at low wind speeds and with low noise level. However, an approach with accurate results, acceptable time consumption, and cost for optimizing this turbine is not reported in the literature.

SOLUSI MODEL LINEAR NAVIER-STOKES-KORTEWEG DI R_+^3 DENGAN SYARAT BATAS SLIP

Jurnal Lebesgue
This article discusses the solution of the linear Navier-Stokes-Korteweg model in  considering slip boundary conditions. This model is often used to describe the two-phase flow of fluids, where there is a phase change at the interface known as the ...
