Applications of the contravariant form of the Navier-Stokes equations [PDF]

The contravariant Navier-Stokes equations in weak conservation form are well suited to certain fluid flow analysis problems. Three dimensional contravariant momentum equations may be used to obtain Navier-Stokes equations in weak conservation form on a ...

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.
