先进反应堆下降段内高普朗特数流体流动的直接数值模拟

Direct Numerical Simulation of High Prandtl Number Fluid Flow in the Downcomer of an Advanced Reactor

Tri Nguyen, Elia Merzari

AI总结:

本研究通过直接数值模拟(DNS)分析先进核反应堆下降段内高普朗特数流体流动,构建数据库以理解流动行为,并评估与改进现有传热关联式。

摘要:

先进核反应堆(Gen IV)的设计涉及一系列影响其安全与性能的流体流动难题。计算所得的 DNS 数据库将有助于理解下降段内的流动行为。最终,我们旨在评估现有传热关联式,并提出若干修改建议。

英文摘要:

The design of advanced nuclear reactors (Gen IV) involves an array of challenging fluid-flow issues that affect its safety and performance. The calculated DNS database will be instrumental in understanding the flow behavior in the downcomer. Ultimately, we aim to evaluate existing heat transfer correlations and some modifications are proposed.
