#### 4.1.4 Analysis of Publication Source  
Another analysis conducted in this query focuses on the publication sources with the highest number of publications. This analysis is particularly valuable for future researchers  
Figure 5: Countries with founding sponsors with the largest number of publications. in this field, as it provides useful insights for making informed decisions when selecting where to publish their findings to maximize reach and impact. From a total of 161 potential journals, the analysis focused on the top 10 journals with the highest number of publications. Additionally, their impact was assessed using the h-index [84] and the SJR metric, which is based on data from Scopus [85]. Figure 6 presents a scatter plot of the top 10 publication sources with the highest number of publications. The x-axis represents the SJR value, while the y-axis represents the number of publications. Additionally, the h-index is visually represented through the color and size of each data point corresponding to the publication sources. In general, the most prominent sources in the graph correspond to those with the highest number of publications, either due to their longevity or their relevance in the field. The sources positioned furthest to the right exhibit the highest impact according to the SJR metric, which evaluates citation quality rather than quantity, based on the last three years of data. Additionally, the size and color of each element in the graph represent the h-index, which reflects the historical impact of the journal. The quartile ranking (2024) of each publication source is also included. Among the top ten publication sources, the four journals that stand out due to their high impact are _Energy_ (published by Elsevier), _Applied Thermal Engineering_ (published by Elsevier), _Physics of Fluids_ (published by AIP Publishing) [86], and _Lecture Notes in Computer Science_ (including the subseries _Lecture Notes in Artificial Intelligence_ and _Lecture Notes in Bioinformatics_, published by Springer). _Lecture Notes in Computer Science_ had a high number of publications and the highest h-index among the listed sources. However, its current impact, as measured by SJR, was relatively low (below 1), suggesting that despite its large volume of publications, its overall influence may be limited. In contrast, _Energy_ and _Applied Thermal Engineering_ had fewer publications but exhibit respectable h-index values and the highest SJR scores among the analyzed sources. These journals represent viable options for researchers seeking to maximize the impact of their publications. However, given their higher impact, publishing in these journals may pose greater challenges. They are particularly relevant for studies integrating the topics of this query with broader research domains. Figure 6: Scatter plot of the number of publications and the impact of the 10 publication sources with the highest number of publications (impact indices used, SJR and the h-index). Another critical aspect in evaluating publication sources is their citation impact. Two analyses were conducted to determine the most optimal journals for publication, based on citation frequency and interconnections. Figure 7a presents an analysis of citation relationships among the publication sources. In this regard, _Physics of Fluids, Energy, Energies_, and _SAE Technical Paper_ (yellow cluster) stood out as the most highly cited sources of publication, demonstrating strong citation interactions with most other sources. However, within the scope of this study, publication sources did not exhibit strong mutual citation relationships. Figure 7b provides a bibliographic coupling analysis of the top 20 publication sources. In this case, \"Physics of Fluids\" emerged as the most frequently cited source of publication, often appearing in co-citations with sources such as \"Ocean Engineering\" and \"IEEE Access\".
