Scientists discover method for sculpting how chemicals spread in fluid flows
Scientists method for sculpting chemicals spread fluid flows
2016/11/29
Art was created with proportions in mind so spaces would make mathematical sense. Now two mathematicians from the University of North Carolina at Chapel Hill and their team have created art of their o...
Compressible fluid flows driven by stochastic forcing
stochastic Navier-Stokes equations compressible fluid random driving force
2012/6/21
We consider the Navier-Stokes system describing the motion of a compressible barotropic fluid driven by stochastic external forces. Our approach is semi-deterministic, based on solving the system for ...
Modified control grid interpolation for the volumetric reconstruction of fluid flows
Modified control grid interpolation volumetric reconstruction fluid flows
2009/12/23
Complex applications in fluid dynamics research often require more highly resolved velocity data than direct measurements or simulations provide. The advent of stereo PIV and PCMR techniques has advan...
Distinguished hyperbolic trajectories in time-dependent fluid flows:analytical and computational approach for velocity fields defined as data sets
Distinguished hyperbolic trajectories time-dependent fluid flows velocity fields
2009/11/12
In this paper we develop analytical and numerical methods for finding special hyperbolic trajectories that govern geometry of Lagrangian structures in time-dependent vector fields. The vector fields (...
On statistical equilibrium in helical fluid flows
statistical equilibrium helical fluid flows
2009/11/9
The statistical mechanics of 3-D helical flows is re-examined for a continuum truncated at a top wavenumber. Based on the principle of equipartition of the flow enstrophy between helical modes, the em...
Numerical Analysis of Fluid Flows within and around Water Drops Translating in the Oil Phase in a Uniform Electric Field
Desalter Fluid dynamics Numerical analysis Polarized charge drop
2009/7/23
The present study was undertaken to improve the understanding of the movement behavior of water drops in the electro-desalter during crude petroleum refining. Fluid flows within and around a single...
Similarity approach to the problem of second grade fluid flows over a stretching sheet
Two-dimensional boundary layer flows Viscoelastic second grade fluid
2010/9/15
This paper presents a study of the two-dimensional boundary layer flows of viscoelastic second grade fluid over a stretching sheet by the similarity method. Exploiting that some features of free-param...
