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 Volume-of-Fluid (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 low-dimensional models. Emphasis is placed on the regime ... -
The Feldstein-Horioka puzzle across EU members: Evidence from the ARDL bounds approach and panel data
(2008)This paper addresses the saving-investment (SI) correlation for the EU 15 member countries, using the ARDL approach and panel regressions. If we accept the Feldstein-Horioka [Feldstein, M. and C. Horioka, 1980, Domestic ... -
GREY WATER FOOTPRINT OF CROPS AND CROP-DERIVED PRODUCTS: ANALYSIS OF CALCULATION METHOD
(2014)The explosive increase in world population, along with the fast socio-economic 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 three-dimensional magnetohydrodynamics
(2004)A lattice kinetic algorithm to simulate three-dimensional (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 3-D MHD turbulence
(2006)A recently proposed lattice Boltzmann kinetic scheme offers a promising tool for simulating complex 3-D 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 low-Pr 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 two-dimensional 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 steady-state 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 low-frequency 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 density-stratified environment. On the basis of the self-similarity ... -
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. Time-variations of film height and ... -
Three-dimensional stability of free convection vortices in the presence of a magnetic field
(2012)Three-dimensional (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 proper-orthogonal-decomposition method is applied to particle-image-velocimetry (PIV) data to extract the most energetic flow structures of vortex-tail interaction. The reconstructed flowfields, in conjunction with ...
