Post test calculation using experimental data from the ROCOM test facility

The following tables contain an overview on the post test calculations of ROCOM experiments using CFD or system codes. In the tables the identifier for the experiment, the project, in that frame the experiment was conducted, and a short description of the experimental boundary conditions are shown. There can be found also the code used for the calculations together with the name of the organisation which performed the corresponding calculation.

Detailed information on the experiments and the calculations can be found in the references shown in the last column of the tables. The references not being a part of the HZDR publication data base are listed below the tables.
