Non-Equilibrium Thermodynamics of Boundary Conditions
In part I a well-known pair of cross phenomena, thermo-osmosis and mechano-caloric effect, in a dense gas is treated by a "thermo-hydrodynamical" method: the FOURIER and NAVIER-STOKES equations are adopted for heat conduction and viscous motion whereas in the boundary conditions MAXWELL'S thermal slip (3.1) and a mechanical surface heat flow (3.7) appear. Both of them are connected by an ONSAGE...
متن کاملPressure Boundary Treatment In Internal Gas Flows At Subsonic Speed Using The DSMC Method
Two numerical procedures in the Direct Simulation Monte Carlo method, applying particle flux conservation at inflow/outflow pressure boundaries, are developed to treat the two most important boundary conditions encountered in micromechanical and vacuum devices involving internal gaseous flows. The first one is for both specified pressures at inlet and exit; while the second one is for specified...
متن کاملComparison of outflow boundary conditions for subsonic aeroacoustic simulations
OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. SUMMARY Aeroacoustics simulations require much more precise boundary conditions than classical aerodynamics. Two classes of non-reflecting boundary conditions for aeroacoustics are compared in the present work: characteristic analysis based methods and Tam...
متن کاملAccounting for Boundary Effects in Nearest - Neighbor
Given n data points in d-dimensional space, nearest-neighbor searching involves determining the nearest of these data points to a given query point. Most averagecase analyses of nearest-neighbor searching algorithms are made under the simplifying assumption that d is fixed and that n is so large relative to d that boundary effects can be ignored. This means that for any query point the statisti...
متن کاملDetermining hydrodynamic boundary conditions from equilibrium fluctuations.
The lack of a first-principles derivation has made the hydrodynamic boundary condition a classical issue for the past century. The fact that the fluid can have interfacial structures adds additional complications and ambiguities to the problem. Here we report the use of molecular dynamics to identify from equilibrium thermal fluctuations the hydrodynamic modes in a fluid confined by solid walls...
