RISEffects of thermal creep and high order slip/jump on natural convection in microchannels
Natural convection gaseous slip flows in open-ended vertical parallel-plate microchannels with symmetric wall heat fluxes are numerically investigated. A second-order model, including thermal creep effects, is considered ...
Mixed convective rarefied flows with symmetric and asymmetric heated walls
Mixed convection gaseous slip flows in an open-ended vertical parallel-plate channel with symmetric and asymmetric
wall temperatures are numerically investigated. Buoyancy effects on developing and fully developed ...
Investigation of Aerodynamic Characteristics of Rarefied Flow around NACA 0012 Airfoil Using DSMC and NS Solvers
In this study, rarefied supersonic and subsonic gas flow around a NACA 0012 airfoil is
simulated using both continuum and particle approaches. Navier Stokes equations subject to
the first order slip/jump boundary conditions are solved...
Thermal rarefied gas flow investigations through micro/nano backward-facing step: Comparison of DSMC and CFD subject to hybrid slip and jump boundary conditions
This paper evaluates the suitability of a newly developed hybrid “Langmuir-Maxwell” and “Langmuir-
Smoluchowski” slip/jump boundary conditions in the Navier-Stokes-Fourier equations for nano/micro
backward-facing step geometry flow...
Effects of High-Order Slip/Jump, Thermal Creep, and Variable Thermophysical Properties on Natural Convection in Microchannels With Constant Wall Heat Fluxes
Natural convection gaseous slip flows in open-ended vertical parallel-plate microchannels with symmetric wall heat fluxes are numerically investigated. A second-order model, including thermal creep effects, is considered for ...
Rarefied gas flow simulations of NACA 0012 airfoil and sharp 25-55-deg biconic subject to high order nonequilibrium boundary conditions in CFD
-of-attack of 0 and 10
degrees and Mach numbers of 0.8 and 2. The sharp 25-55-deg biconic case is simulated at Mach of 15.6.
The simulation results obtained for the NACA0012 airfoil show that the combination of the second
order slip/jump...
Extension of a Second Order Velocity Slip/Temperature Jump Boundary Condition to Simulate High Speed Micro/Nanoflows
In the current work, for the first time, we extend the application of a second order slip/jump equations
introduced by Karniadakis et al. for the simulation of high speed, high Knudsen (Kn) number flows over
flat plate and cylinder...
Comprehensive assessment of newly-developed slip-jump boundary conditions in high-speed rarefied gas flow simulations
n this paper we numerically evaluate the recently developed Aoki et al. slip and jump conditions in high-speed rarefied gas flows for the first time. These slip and jump conditions are developed to be employed with the ...
