Effects of wall roughness on flow in nanochannels
(2009)Nonequilibrium molecular dynamics simulation is applied to investigate the effect of periodic wall roughness on the flow of liquid argon through krypton nanochannels. The effect of the length of a rectangular protrusion ... -
AN INVISCID INVESTIGATION OF THE INITIATION OF ROLL WAVES IN HORIZONTAL GAS-LIQUID FLOWS
(1994)A model with constant vorticity in the liquid phase has been applied to the study of interfacial waves between two inviscid fluids in relative motion, in order to take into account the shear induced into the liquid by the ... -
On the stick-slip flow from slit and cylindrical dies of a Phan-Thien and Tanner fluid model. II. Linear stability analysis
(2013)During extrusion of viscoelastic fluids various flow instabilities may arise resulting in a distorted free surface. In order to investigate the factors generating these instabilities we performed a linear stability analysis ... -
Parametric stability and dynamic buckling of an encapsulated microbubble subject to acoustic disturbances
(2011)Stability analysis of the radial pulsations of a gas microbubble that is encapsulated by a thin viscoelastic shell and surrounded by an ideal incompressible liquid is carried out. Small axisymmetric disturbances in the ... -
Simulations of insonated contrast agents: Saturation and transient break-up
(2013)Under insonation contrast agents are known to perform nonlinear pulsations and deform statically, in the form of buckling, or dynamically via parametric mode excitation, and often exhibit jetting and break-up like bubbles ... -
Surface wettability effects on flow in rough wall nanochannels
(2012)The effect of rough-wall/fluid interaction on flow in nanochannels is investigated by NEMD. Hydrophobic and hydrophilic surfaces are studied for walls with nearly atomic-size rectangular protrusions and cavities. Our NEMD ... -
Transport properties of liquid argon in krypton nanochannels: Anisotropy and non-homogeneity introduced by the solid walls
(2009)In this work we calculate the transport properties of liquid argon flowing through a nanochannel formed by krypton walls. Non-equilibrium Molecular dynamics (NEMD) simulations are performed assuming flow conditions ...
