Study on a Numerical Simulation for Thermal-Hydraulic Phenomena of Multiphase, Multicomponent Flows; Modeling of Multiphase, Multicomponent Flows with Phase Transition
None 炉心損傷事故の安全解析コードにおける多成分多相流の熱流動現象の数値シミュレーション技術の高度化を図ることは、安全評価の信頼度を向上する上で重要な課題の一つである。核燃料サイクル開発機構と九州大学によって実施された本共同研究では、炉心損傷事故(CDA)を解析する高速炉安全解析コードに適用可能な多成分系蒸発/凝縮現象の一般化モデルを新たに開発した。このモデルは、CDA条件下での多成分相変化現象を模擬するため、蒸発/凝縮過程の特性を熱伝達および質的拡散による律速モデルを用いて記述している。さらに、既存の多成分凝縮実験および新たに実施した気泡凝縮実験の解析によって、本モデルが非凝縮性ガスを含む蒸気の凝縮過程を適切に再現することを確認し、用いられたモデル化手法の妥当性を示した。
