Validation Database (KIT Sample Clauses

Validation Database (KIT. ‌ Model validation involves a comparison of model predictions with experimental measurements. Validation should be performed using several experiments that are within the model’s range of applicability. For code validation high quality experimental data is important; a comparison between a numerical simulation and poor quality experimental data cannot reliably indicate that a numerical model reflects real physics. Building a high-quality validation database is the first step in a successful validation exercise. To achieve the goal of successful validation applied to hydrogen safety analysis, a validation database containing high quality experiments and covering different physical phenomena has been established. The validation database has been created using the following headings: • Ignition and fires of hydrogen gas • Release and distribution of gaseous and liquid hydrogen • Deflagration of hydrogen gas • Detonation of hydrogen gas • Deflagration to detonation transition (DDT) With each experiment, detailed information is given in a consistent format which is summarized as follows: • Summary • Author • Experimental Setup • Objective of experiment • Applicable calculations • Experimental procedure • Experimental data • Performed simulation • Reference • Comment The above headings provide a detailed description of each experiment, including background, preparation, experimental procedure, results, the related numerical works and references. In addition, to provide an acceptable level of quality assurance, an experimental evaluation procedure was introduced for the validation database. Following this process, each experiment should be evaluated by at least two experts who have experience in numerical simulation or experimentation. The experiments which are evaluated as high quality are included in the database, but the experiments which are regarded as lower quality should be revised, abandoned or used with caution. In the validation database the experimental setup is presented and the experimental data and results are publicly available. A short description of each of the experiments included in the validation database is provided in Appendix 2 (Section 9.2). Details of each of these experiments, including the experimental setup and results, are provided in full in the validation database of XXXXXX, which is available on the XXXXXX website (xxx.xxxxxxx-xxx.xx).
