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 ...

Study on the Temporal and Spatial Evolution Mechanism of Rotating Cavitation in the First Stage Impeller of LNG Submersible Pump With Two‐Stage Splitter Blades

Energy Science &Engineering, EarlyView.
ABSTRACT This study establishes a full‐flow passage numerical model of an LNG submerged pump equipped with two‐stage splitter blades through three‐dimensional modeling. Numerical simulations validated by liquid nitrogen experiments demonstrate that at 1.4 times the design flow rate, the peak efficiency reaches 60.6%, with a maximum head of 194.93 m ...

Global Well-Posedness and Long Time Decay of Fractional Navier-Stokes Equations in Fourier-Besov Spaces

Abstract and Applied Analysis, 2014
We study the Cauchy problem of the fractional Navier-Stokes equations in critical Fourier-Besov spaces FB˙p,q1-2β+3/p′. Some properties of Fourier-Besov spaces have been discussed, and we prove a general global well-posedness result which covers some ...
