3D simulation study on plasma diffusion process in vacuum hydrogen ion source

This dataset is derived from numerical simulation results of the plasma discharge process, and its generation and processing procedures are as follows: First, the three-dimensional mesh generation of the simulation region is completed using Gambit software (download link: https://www.gambitlang.org/), generating the 3D.msh file that records the distribution of spatial discrete elements. Then, the mesh file is imported into Ansys Fluent software (download link: https://www.ansys.com/zh-CN/products/fluids/ansys-fluent); after configuring the discharge physical model, initial parameters, and boundary conditions, the simulation calculation is initiated to obtain raw simulation data including particle parameters and discharge information. Finally, classified extraction is performed on the raw data to obtain element-specific results and numerical data corresponding to visual charts.The spatial information involved in this dataset corresponds to the three-dimensional geometric computational domain of the simulation region. The spatial resolution is determined by the mesh element density in the 3D.msh file, where the mesh serves as the discretized spatial unit of the computational domain. The files and their contents included in the dataset are as follows: D.dat records the simulation results of deuterium, covering parameters such as the number density (unit: m⁻³) and axial velocity (unit: m/s) of deuterium particles; Zr.dat records the simulation results of zirconium, and also contains discharge information including current density (unit: A/m²) and electron temperature (unit: eV); 3D.msh is the mesh position data, which can be imported via Ansys Fluent to restore the simulation computational domain; "temperature" is the numerical data for the temperature distribution chart of each element, recording the element temperature (unit: eV) at different spatial positions; "ionflux" is the numerical data for the flux comparison chart, including the particle flux of deuterium and zirconium.There is no data missing in this dataset, and all valid simulation data have been classified and archived. Data errors mainly stem from the simplified assumptions of physical processes in the simulation model and numerical errors from mesh discretization; the error range falls within the conventional acceptable range for plasma numerical simulations, meeting the research accuracy requirements of this field. After importing the 3D.msh mesh file via Ansys Fluent, data files such as D.dat and Zr.dat can be loaded to read the corresponding content.
