HTR-1.3 solver: Predicting electrified combustion using the hypersonic task-based research solver

This manuscript presents an updated open-source version of the Hypersonics Task-based Research (HTR) solver. The solver, whose main features are presented in Di Renzo et al. (2020) [9] and Di Renzo & Pirozzoli (2021) [10], is designed for direct numerical simulation of reacting flows at high Reynolds numbers. This new version extends the applications of the HTR solver to turbulent combustion in the presence of external electric fields. In particular, a new distributed Poisson solver compatible with heterogeneous architectures has been incorporated in the algorithm to compute the electric potential distribution in bi-periodic configurations. The drift fluxes of the electrically charged species are now included in the transport equations using a targeted essentially non-oscillatory scheme. A verification of these new features of the solver is provided using one-dimensional burner stabilized flames, whereas a three dimensional turbulent flame is utilized to discuss the scalability of the proposed numerical tool.

本文介绍了高超声速任务型研究（Hypersonics Task-based Research, HTR）求解器的更新开源版本。该求解器的核心特性已在Di Renzo等人（2020年）[9]以及Di Renzo与Pirozzoli（2021年）[10]的研究中予以阐述，其初始设计用于开展高雷诺数下反应流的直接数值模拟（direct numerical simulation）。本次更新的版本将HTR求解器的应用范围拓展至外电场存在条件下的湍流燃烧场景。具体而言，算法中新增了兼容异构架构（heterogeneous architecture）的分布式泊松求解器（Poisson solver），用于计算双周期配置（bi-periodic configuration）下的电势分布。当前，算法已通过靶向本质非振荡格式将带电组分的漂移通量纳入输运方程（transport equation）中。本文通过一维燃烧器稳定火焰对求解器的上述新增特性开展验证，同时利用三维湍流火焰来探讨所提出数值工具的可扩展性（scalability）。
