Bubble rise dynamics in a viscoplastic material
(2015)The axisymmetric dynamics of a bubble rising in a Bingham fluid under the action of buoyancy is studied. The VolumeofFluid (VOF) method is used to solve the equations of mass and momentum conservation, coupled to an ... 
Extreme solitary waves on falling liquid films
(2014)Direct numerical simulation (DNS) of liquid film flow is used to compute fully developed solitary waves and to compare their characteristics with the predictions of lowdimensional models. Emphasis is placed on the regime ... 
The FeldsteinHorioka puzzle across EU members: Evidence from the ARDL bounds approach and panel data
(2008)This paper addresses the savinginvestment (SI) correlation for the EU 15 member countries, using the ARDL approach and panel regressions. If we accept the FeldsteinHorioka [Feldstein, M. and C. Horioka, 1980, Domestic ... 
GREY WATER FOOTPRINT OF CROPS AND CROPDERIVED PRODUCTS: ANALYSIS OF CALCULATION METHOD
(2014)The explosive increase in world population, along with the fast socioeconomic development, have led to an increased water demand; the impact of global water resource consumption is mapped with the "water footprint", which ... 
Lattice kinetic simulations in threedimensional magnetohydrodynamics
(2004)A lattice kinetic algorithm to simulate threedimensional (3D) incompressible magnetohydrodynamics is presented. The fluid is monitored by a distribution function, which obeys a scalar kinetic equation, subject to an ... 
Lattice kinetic simulations of 3D MHD turbulence
(2006)A recently proposed lattice Boltzmann kinetic scheme offers a promising tool for simulating complex 3D MHD flows. The algorithm is based on the BGK modeling of the collision term. The conventional approach for implementing ... 
Magnetic field effect on the cooling of a lowPr fluid in a vertical cylinder
(2010)Results of direct numerical simulations are presented for the transient and turbulent natural convection cooling of an initially isothermal quiescent liquid metal placed in a vertical cylinder in the presence of a vertical ... 
MHD natural convection in a laterally and volumetrically heated square cavity
(2005)A numerical study is presented of unsteady twodimensional natural convection of an electrically conducting fluid in a laterally and volumetrically heated square cavity under the influence of a magnetic field. The flow is ... 
Modeling of ITER related vacuum gas pumping distribution systems
(2013)A novel algorithm recently developed to solve steadystate isothermal vacuum gas dynamics flows through pipe networks consisting of long tubes is extended to include, in addition to long channels, channels of moderate ... 
Nonlinear dynamics of inclined films under lowfrequency forcing
(2004)The evolution of an inclined liquid film, subjected to regular inlet disturbances of small frequency, f, is studied experimentally and computationally. The fluorescence imaging method is used to quantitatively document ... 
On the entrainment coefficient in negatively buoyant jets
(2008)Integral models proposed to simulate positively buoyant jets are used to model Jets with negative or reversing buoyancy issuing into a calm, homogeneous or densitystratified environment. On the basis of the selfsimilarity ... 
RECURRENCE QUANTIFICATION ANALYSIS OF TEMPERATURE FLUCTUATIONS IN A HORIZONTAL ROUND HEATED TURBULENT JET
(2009)We present an analysis of temperature fluctuations in a horizontal round heated turbulent jet. Instantaneous temperature time series were recorded at several points along a horizontal line in the plane of symmetry of the ... 
Solitary waves on inclined films: their characteristics and the effects on wall shear stress
(2006)The properties of solitary waves, developing from inlet disturbances of controlled frequency along an inclined film flow, are systematically studied experimentally and computationally. Timevariations of film height and ... 
Threedimensional stability of free convection vortices in the presence of a magnetic field
(2012)Threedimensional (3D) stability of 2D vortical flow of a liquid metal in a cavity of square cross section is examined. Vortices are produced as a result of free convection and internal heating in the cavity in the presence ... 
Vortex buffeting of aircraft tail: Interpretation via proper orthogonal decomposition
(2005)The properorthogonaldecomposition method is applied to particleimagevelocimetry (PIV) data to extract the most energetic flow structures of vortextail interaction. The reconstructed flowfields, in conjunction with ...
