Direct numerical simulation of particle laden flow in a human airway bifurcation model
(2016)During the delivery of inhaled medicines, and depending on the size distribution of the particles in the formulation, airway bifurcations are areas of preferential deposition. Previous studies of laminar flow through airway ...

Direct numerical simulation of turbulent liquid metal flow entering a magnetic field
(2013)This paper presents direct numerical simulations (DNS) of fully developed turbulent liquidmetal flow in a circular duct entering a magnetic field. The case of a magnetohydrodynamic flow leaving a strong magnetic field has ...

Article
Dispersedphase structural anisotropy in homogeneous magnetohydrodynamic turbulence at low magnetic Reynolds number
(2008)A new tensor statistic, the dispersedphase structure dimensionality Dp, is defined to describe the preferred orientation of clusters of discrete bodies. The evolution of Dp is calculated via direct numerical simulations ...

Article
Dispersedphase structure in sheared MHD turbulence
(2012)Direct numerical simulations are performed to examine particle dispersion in homogeneous turbulence subjected to mean shear and an externally applied magnetic field. We employ the Brucker et al. algorithm for simulating ...

Article
Dynamical models for fault detection in squirrel cage induction motors
(2007)Induction motors are the dominant components in industrial processes involving electromechanical energy conversion. Safety, reliability and efficiency are major concerns in modern induction motor applications. Since detecting ...

Article
Effects of the consistency of the fringing magnetic field on direct numerical simulations of liquidmetal flow
(2011)We investigate the effects of the consistency of strong fringing decreasing magnetic fields on numerical simulations of classical experimental data. Studies about fringing magnetic fields have attracted the attention of ...

Article
Efficient treatment of complex geometries for large eddy simulations of turbulent flows
(2004)Incompressible turbulent flow over a backward facing step at Reh=5100 is investigated by large eddy simulations (LES). The ratio of the oncoming boundary layer thickness δ to the step height h was set to 1.2. Additionally ...

Representing anisotropy of twopoint secondorder turbulence velocity correlations using structure tensors
(2008)A locally homogeneous representation for the twopoint, secondorder turbulent velocity fluctuation Rij(x,r) = 〈u′i(x)u′i(x+r)〉 is formulated in terms of three linearly independent structure tensors [Kassinos et al., J. ...
