3D Features in the Calendering of Thermoplastics: A Computational Investigation
(2014)We present results of a fully three-dimensional computational study of the calendering process of thermoplastics using the fluid dynamics software OpenFOAM. Our aim is to elucidate unique 3D features of the process, such ... -
Computer-aided estimation of acetone, methyl acetate, and chloroform diffusion coefficients in poly(vinyl acetate)
(2003)The diffusion coefficients of acetone, methyl acetate, and chloroform in amorphous poly(vinyl acetate) are estimated using the solvent evaporation method. The evaporation process from polymer solutions, cast in the form ... -
A dissipative particle dynamics study of flow in periodically grooved nanochannels
(2012)The effect of periodic rectangular wall roughness on planar nanochannel flow is investigated by dissipative particle dynamics simulation. The wall protrusion length is varied, and its effect on the flow is examined. Analysis ... -
The Free (Open) Boundary Condition at inflow boundaries
(2012)The Free (or Open) Boundary Condition (FBC, OBC) was proposed by Papanastasiou et al. (A new outflow boundary condition, Int. J. Numer. Meth. Fluids 14 (1992) 587-608) to handle truncated domains with synthetic boundaries ... -
Non-isothermal bubble rise: non-monotonic dependence of surface tension on temperature
(2015)We study the motion of a bubble driven by buoyancy and thermocapillarity in a tube with a non-uniformly heated walls, containing a so-called 'self-rewetting fluid'; the surface tension of the latter exhibits a parabolic ... -
System dynamics revealed by recurrence quantification analysis: Application to molecular dynamics simulations
(2007)The present work examines the applicability and efficacy of recurrence plots and recurrence quantification analysis in interpreting statistical-mechanics-based simulations of classical fluids and solids. We analyze temperature ... -
Unified description of size effects of transport properties of liquids flowing in nanochannels
(2012)The present work connects transport properties of simple fluids flowing in nanochannels: the diffusion coefficient, the shear viscosity and the thermal conductivity. We used non-equilibrium molecular dynamics (NEMD) ...
