Data accompanying Chapter 5 of the PhD Dissertation: Methanol Sprays in Marine Internal Combustion Engines: A Computational Fluid Dynamics Approach

<strong>Introduction</strong>This dataset contains the results and inputs files collected as part of the Chapter 5 in the doctoral thesis of Mr. Konstantinos Zoumpourlos, Dipl.-Ing in Delft University of Technology, 2022-2026.The present dataset is made public to act both as supplementary data for the publications of K. Zoumpourlos and to offer other researchers the ability to use this data in their own work.This data is part of the MENENS project (Methanol als Energiestap Naar Emissieloze Nederlandse Scheepvaart).The project is funded by the Netherlands Enterprise Agency (RVO: Rijksdienst voor Ondernemend Nederland) under the grant number MOB21012.<br><strong>Purpose of the dataset</strong>The purpose of these simulations is to recreate the spray formation for Engine Combustion Network (ECN) Spray D non-reacting experiment using n-dodecane as a diesel surrogate. The validated diesel injection model is converted for methanol injection accounting for marine dual-fuel engine conditions. The two sprays are compared based on their spray structure, evaporation and cooling effect using the CFD simulation results.<br><strong>Description of the dataset</strong>Input files for the CFD diesel baseline validation, methanol comparison case, and 6 additional case studies (equal energy and ambient temperature studies) conducted in CONVERGE-CFD 3.0.Additional mean-value 0D and 3D spatial data are included for the simulation cases.The validation cases are denoted by the zip file name including the fuel name, the injection pressure and the ambient temperature environment corresponding to each individual simulation case. Inside each directory, the input files (.dat and .in files), 0D results (text format .out files) and 3D results (text format .h5 files) are denoted by their respective directory names.<br><strong>Dependencies</strong>To open the simulation input files CONVERGE 3.0 is needed. However, for the inspection of the modelling constants, initial &amp; boundary conditions, it is possible to use a text editor to read the inputs. The 0D simulation results can be opened using Excel, Matlab, or other table reading software. Lastly, the 3D output files can be accessed using any CFD post-processing software such as Paraview, Tecplot, etc.

### 数据集概述
本数据集收录了康斯坦丁诺斯·祖姆普洛斯（Konstantinos Zoumpourlos）先生的相关研究成果与输入文件，其于2022-2026年在代尔夫特理工大学攻读工学博士（Dipl.-Ing）学位，相关内容出自其博士论文第五章。本数据集公开发布，既可作为K.祖姆普洛斯已发表论文的补充数据，也可为其他研究人员将本数据应用于自身研究工作提供支持。本数据隶属于MENENS项目（甲醇作为荷兰零排放航运的能源载体，Methanol als Energiestap Naar Emissieloze Nederlandse Scheepvaart），该项目由荷兰企业局（Rijksdienst voor Ondernemend Nederland，简称RVO）以编号MOB21012的资助项目支持。

### 数据集用途
本系列仿真旨在复现采用正十二烷作为柴油替代燃料的发动机燃烧网络（Engine Combustion Network，ECN）Spray D无反应实验的喷雾形成过程。经验证的柴油喷射模型将适配船用双燃料发动机工况，转换为甲醇喷射模型。基于计算流体动力学（Computational Fluid Dynamics，简称CFD）仿真结果，从喷雾结构、蒸发及冷却效应三方面对两种燃料的喷雾过程进行对比分析。

### 数据集说明
本数据集包含用于CFD柴油基线验证、甲醇对比工况以及6项额外工况研究（等能量与环境温度工况）的输入文件，所有工况均基于CONVERGE-CFD 3.0平台开展。此外，还包含各仿真工况的平均零维（0D）及三维（3D）空间数据。验证工况通过压缩包文件名标识，文件名包含对应单个仿真工况的燃料名称、喷射压力及环境温度参数。每个目录下，输入文件（.dat与.in格式文件）、零维仿真结果（.out格式文本文件）及三维仿真结果（.h5格式文本文件）均以各自目录名区分。

### 依赖条件
打开仿真输入文件需使用CONVERGE 3.0软件。若仅需查看建模常数、初始条件与边界条件，可直接通过文本编辑器读取输入文件。零维仿真结果可通过Excel、Matlab或其他表格读取软件打开。三维输出文件则可通过任意CFD后处理软件（如Paraview、Tecplot等）访问。
