Gas-kinetic scheme for rarefied flow simulation
For increasingly rarefied flowfields, the predictions from continuum formulation, such as the Navier–Stokes equations lose accuracy. These inaccuracies are attributed primarily to the linear approximations of the stress and heat flux terms in the Navier– Stokes equations. The inclusion of higher order terms, such as Burnett, or high-order moment equations, could improve the predictive capabilit...
متن کاملDSMC Simulation with Gas-Surface Interaction Models in Hypersonic Rarefied Flow
A DSMC (direct simulation Monte Carlo) simulation using Dynamical Molecular Collision (DMC) model based on Molecular Dynamics (MD) calculation with various gas-surface interaction models is applied for solving the two-dimensional nonequilibrium hypersonic rarefied flow over a flat plate with leading edge angle. The gas surface interaction models adopt the diffuse reflection model, the Cercignan...
متن کاملAssessment of Gas-Surface Interaction Models in DSMC Analysis of Rarefied Hypersonic Flow
The aerothermodynamics of spacecraft entering a planetary atmosphere are sensitive to the level of gas-surface accommodation governed by the gas-surface interaction. The modeling of this interaction plays an integral role in the solid surface boundary condition of the Direct Simulation Monte Carlo (DSMC) method. The Maxwell, and Cercignani, Lampis and Lord (CLL) gas-surface interaction models a...
متن کاملAssessment of Gas–Surface Interaction Models for Computation of Rarefied Hypersonic Flow
Among the few classes of computational approaches for examining rarefied gas dynamics, the most widely used technique for spatial scales relevant to suborbital spaceflight is the direct simulationMonte Carlo method. One area in which the direct simulation Monte Carlo method can be improved is the numerical modeling of the interactions between gas molecules and solid surfaces. Gas–surface intera...
متن کاملFlow of a Rarefied Gas between Parallel and Almost Parallel Plates
Rarefied gas flows in ultra-thin film slider bearings are studied in a wide range of Knudsen numbers. The generalized Reynolds equation first derived by Fukui and Kaneko [1], [2] has been extended by allowing for bounding surfaces with different physical structures, as an issue of relevance for applications. Since the solution of this equation requires that the Poiseuille and Couette flow rates...
