RISStudy of Convergence Time for Rarefied Gas Simulations Using an Unstructured DSMC Solver
This article studies the required convergence time for direct-simulation Monte Carlo (DSMC) simulations of rarefied gas flows. An arbitrary-geometry DSMC solver (RGS2D) with an efficient particle-tracking algorithm is ...
A Novel Algorithm for Implementing Specified Wall Hat Flux in DSMC: Application to Micro/Nano Flows and Hypersonic Flows
This paper introduces a modified version of the iterative technique (IT) technique called the modified iterative technique (MIT) which implements a desirable wall heat flux distribution over the wall for rarefied gas ...
Evaluation of New Collision-Pair Selection Models in DSMC
The current paper investigates new collision-pair selection procedures in Direct Simulation Monte Carlo (DSMC) method. Collision partner selection based on the random procedure from near neighbor particles and deterministic ...
On the Consequences of Successively Repeated Collisions in No-Time-Counter Collision Scheme in DSMC
The current paper investigates the appropriateness and consequences of avoiding successively repeated collisions usually recommended in the Direct Simulation Monte Carlo (DSMC) solvers, which use the No Time Counter (NTC) ...
Mass flow rate prediction of pressure–temperature-driven gas flows through micro/nanoscale channels
In this paper, we study mass flow rate of rarefied gas flow through micro/nanoscale channels
under simultaneous thermal and pressure gradients using the direct simulation Monte Carlo (DSMC) method.
We first ...
Wall heat transfer effects on the hydro/thermal behaviour of Poiseuille flow in micro/nanochannels
We investigate effects of wall heat transfer on the structure of pressure driven flow in micro/nanochannels using the Direct Simulation Monte Carlo method. The effects of non-zero wall heat flux on the pressure distribution, ...

DSMC Simulation of rarefied gas flows under Cooling Conditions Using a New Iterative Wall Heat Flux Specifying Technique
Micro/nano geometries with specified wall heat flux are widely encountered in electronic cooling and micro-
