Natural convection of liquid metal in a vertical annulus with lateral and volumetric heating in the presence of a horizontal magnetic field
(2011)MHD free convection of a liquid metal is studied in a closed vertical annulus in which the upper and bottom walls are adiabatic while the cylindrical walls are kept at different temperatures. The flow is driven by two ... -
Non-invasive measurement of tibialis anterior muscle temperature during rest, cycling exercise and post-exercise recovery
(2015)We introduce a non-invasive and accurate method to assess tibialis anterior muscle temperature (Tm) during rest, cycling exercise, and post-exercise recovery using the insulation disk (INDISK) technique. Twenty-six healthy ... -
Nonlinear oscillations and collapse of elongated bubbles subject to weak viscous effects
(2005)The weak viscous oscillations of a bubble are examined, in response to an elongation that perturbs the initial spherical shape at equilibrium. The flow field in the surrounding liquid is split in a rotational and an ... -
Nonlinear resonance in viscous films on inclined wavy planes
(2009)We study nonlinear resonance in viscous gravity-driven films flowing over undulated substrates. Numerical solution of the full, steady Navier-Stokes equations is used to follow the emergence of the first few free-surface ... -
Nonlinear time series analysis and clustering for jet axis identification in vertical turbulent heated jets
(2014)In the present work we approach the hydrodynamic problem of discriminating the state of the turbulent fluid region as a function of the distance from the axis of a turbulent jet axis. More specifically, we analyzed temperature ... -
Numerical investigation of momentum exchange between particles and coherent structures in low Re turbulent channel flow
(2011)The interaction between particles and coherent structures is studied by using discrete particle simulation combined with direct numerical simulation of gaseous flow in a vertical channel. A conditional sampling scheme is ... -
A numerical study of interfacial transport to a gas-sheared wavy liquid
(1998)Interfacial transport of a passive scalar from a gas to a thin liquid film is considered. The base flow in the liquid is laminar, with linear velocity profile produced by gas shear. The velocity disturbances imposed by ... -
Parameters Affecting Slip Length at the Nanoscale
(2013)We investigate liquid flows in various nanochannels and present the effect of all physical parameters affecting slip length at the boundary using molecular dynamics simulations. Our computational model shows that slip ... -
Performance evaluation of an automatic transfer line with WIP scrapping during long failures
(2007)We develop a model of a failure-prone, bufferless, paced, automatic transfer line in which material flows through a number of workstations in series, receiving continuous processing along each workstation. When a workstation ... -
The primary instability of falling films in the presence of soluble surfactants
(2013)We investigate the linear stability of a film flowing down a solid substrate in the presence of soluble surfactants. The Navier-Stokes equations for the liquid motion are considered, together with advection-diffusion ... -
Refined solutions of externally induced sloshing in half-full spherical containers
(2003)A mathematical model is developed for calculating liquid sloshing effects such as hydrodynamic pressures and forces in half-full spherical containers under arbitrary external excitation. The velocity potential is expressed ... -
Shear stress estimation in the linear zone over impermeable and permeable beds in open channels
(2015)This paper investigates the shear stresses in the linear zone of open channel flows with permeable and impermeable bed. The permeable bed is simulated using a flexible vegetation of 2 cm thickness. Laboratory experiments ... -
Static response and stability of coated microbubbles-multiplicity of solutions and parameter estimation
(2014)The static response of a coated microbubble subject to an external pressure distribution is investigated, in order to identify different response patterns with varying viscoelastic properties of the shell. Theoretical and ... -
Stochastic analysis and prioritization of the influence of parameter uncertainty on the predicted pressure profile in heterogeneous, unsaturated soils
(2006)This article utilizes a Monte Carlo stochastic framework to investigate the influence on the mean and variance of the predicted mean pressure head profile of statistical assumptions regarding the parameters that enter the ... -
A study of CaCO3 scale formation and inhibition in RO and NF membrane processes
(2007)The formation of CaCO3 deposits on RO and NF membranes was investigated in connection with permeate flux decline. Experiments, in the presence and absence of scale inhibitors, were carried out in a cross-flow membrane test ... -
