Similarity Parameters and Scaling Laws for Hall Thrusters

Datasets correspond to the numerical model results and experimental data from the research paper: T. Lafleur and P. Chabert, "Similarity Parameters and Scaling Laws", Plasma Sources Science and Technology (2025), https://iopscience.iop.org/article/10.1088/1361-6595/add562 The file "rate_coefficients.xlsx" provides the computed rate coefficient data as a function of electron temperature, T_e, used for the propellants xenon (Xe), krypton (Kr), and argon (Ar). Each column in the file is labelled according to a specific variable of interest, which includes the ionization rate coefficient K_iz, the momentum transfer rate coefficient, K_m, and the average collisional energy loss, varepsilon_c. The file "experimental_data.xlsx" summarizes experimental data taken from the literature for xenon and krypton, and which is used for validation of the numerical model. The data has been taken from the following references: J. M. Sankovic, J. A. Hamley, and T. W. Haag, "Performance evaluation of the russian spt-100 thruster at nasa lerc", in IEPC Conference, IEPC-93-094 (1994). M.R. Nakles, W.A. Hargus Jr, J.J. Delgado, and R.L. Corey, "A performance comparison of xenon and krypton propellant on an spt-100 hall thruster", in IEPC Conference, IEPC-2011-003 (2011). The file "model_validation_data.xlsx" provides the numerical model results for the relevant propellant and fixed operating condition given in the sheet name. The columns correspond to a specific relevant variable, such as thrust. The files "xenon_lambda_0_6.xlsx", "xenon_lambda_1.xlsx", and "xenon_lambda_1_8.xlsx" correspond to model results performed with the similarity parameter lambda = 0.6, lambda = 1, or lambda = 1.8 respectively. Each sheet corresponds to a specific variable calculated on a 2D "grid" associated with different values of the similarity parameters alpha and beta. The sheet labels note the propellant (xenon in this case) as well as the quantity shown, such as the specific impulse (Isp) at a given value of the normalized discharge current (i.e. Id_bar). The file "propellants_lambda_1.xlsx" is similar to the above files for xenon, but instead provide data for xenon, krypton, and argon at lambda = 1 and for Id_bar = 1.2 or Id_bar = 1.4.本数据集对应发表于《Plasma Sources Science and Technology》2025年的研究论文"Similarity Parameters and Scaling Laws"中的数值模型结果与实验数据，作者为T. Lafleur与P. Chabert，论文链接：https://iopscience.iop.org/article/10.1088/1361-6595/add562。 文件"rate_coefficients.xlsx"提供了氙(Xe)、氪(Kr)与氩(Ar)三种推进剂(propellant)的电子温度(T_e)相关计算得到的速率系数数据。文件内各列按关注的特定变量标注，涵盖电离速率系数K_iz、动量传递速率系数K_m以及平均碰撞能量损失varepsilon_c。 文件"experimental_data.xlsx"汇总了来自公开文献的氙与氪的实验数据，用于数值模型的验证。本部分实验数据引自以下两篇文献： 1. J. M. Sankovic、J. A. Hamley及T. W. Haag，"Performance evaluation of the russian spt-100 thruster at nasa lerc"，收录于IEPC会议，编号IEPC-93-094（1994年）。 2. M.R. Nakles、W.A. Hargus Jr、J.J. Delgado与R.L. Corey，"A performance comparison of xenon and krypton propellant on an spt-100 hall thruster"，收录于IEPC会议，编号IEPC-2011-003（2011年）。 文件"model_validation_data.xlsx"提供了对应推进剂的数值模型结果，以及工作表名称中指定的固定工况条件。各列对应特定相关变量，例如推力(thrust)。 文件"xenon_lambda_0_6.xlsx"、"xenon_lambda_1.xlsx"与"xenon_lambda_1_8.xlsx"分别对应相似参数(lambda)为0.6、1与1.8时的模型计算结果。每个工作表对应基于二维"网格"计算得到的特定变量，该网格关联相似参数alpha与beta的不同取值。工作表标签标注了推进剂（此处为氙）以及所展示的物理量，例如归一化放电电流(Id_bar)对应的比冲(Isp)。 文件"propellants_lambda_1.xlsx"与上述氙相关文件格式一致，但包含了相似参数lambda=1且归一化放电电流Id_bar为1.2或1.4时，氙、氪与氩三种推进剂的相关数据。
