The fidelity of DSMC method to analyze the aerothermodynamics of the pure continuum flow regime
International Journal of Thermofluids, 2020 The statistical probabilistic Direct Simulation Monte Carlo (DSMC) method was developed to interrogate the flow regime, in which thermal non-equilibrium exists and flow properties are non-continuous.

Application of the DSMC Method to Particle Simulation
JAPANESE JOURNAL OF MULTIPHASE FLOW, 1994 もう既に聞き飽きた感もあるが、計算機環境の発達によりさまざまな現象が数値シミュレーションにより取り扱われるようになった。混相流のような複雑な流れに対しても、流動を数値シミュレーションにより再現する試みが果敢になされている。最近では、ワークステーションの大幅な能力向上に代表される計算機のダウンサイジングにより、このような数値シミュレーションがより身近なものとなりつつあるのではないだろうか。混相流は時間的および空間的にさまざまなスケールの現象を含んでいるが、計算機の演算能力と記憶容量の増大は、よりミクロな視点に基づくモデルに立脚した数値シミュレーションを可能にする。固気二相流の分野では現在、固体粒子群の運動を個々の粒子レベルでモデル化するラグランジュ型の数値計算が盛んに行われている ...
