This paper presents a compilation and discussion of the results supplied by HySafe partners participating in the Standard Benchmark Exercise Problem (SBEP) V1, which is based on an experiment on hydrogen release, mixing and distribution inside a vessel. Each partner had his own point of view of the problem and used a different approach to the solution. The main characteristics of the models employed for the calculations are compared. The comparison between results, together with the experimental data when available, is made. Relative deviations of each model from the experimental values are also included. Explanations and interpretations of the results are presented, together with some useful conclusions for future work.
