Acceleration schemes of the discrete velocity method: Gaseous flows in rectangular microchannels
(2003)The convergence rate of the discrete velocity method (DVM), which has been applied extensively in the area of rarefied gas dynamics, is studied via a Fourier stability analysis. The spectral radius of the continuum form ... -
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 ... -
Rarefied gas flow through a cylindrical tube due to a small pressure difference
(2013)Flow of a rarefied gas through a cylindrical tube connecting two reservoirs maintained at a small pressure difference is considered using the axisymmetric version of the linearised BGK kinetic model equation subject to ... -
Single phase materials based on Co-doped SrTiO3 for mixed ionic-electronic conductors applications
(2012)In the present work the effect of cobalt oxide addition on the structural and electrical properties of strontium titanate is examined. The SrTi1-xCoxO3-delta (0 <= x <= 0.4) samples were synthesized according to solid state ... -
Stability of confined thin-walled steel cylinders under external pressure
(2009)The present paper investigates the structural stability of thin-walled steel cylinders surrounded by an elastic medium, subjected to uniform external pressure. A two-dimensional model is developed, assuming no variation ... -
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) ... -
Vacancy effect on the elastic constants of layer-structured nanomaterials
(2009)Layer-structured nanomaterials where alternating layers of nanocrystallites meet along high angle grain boundaries constitute a special category of nanomaterials. In the present study we investigated the effect of the ...
