Abstract:

Between 1984 and 1992 four major test series were performed in the HDR containment encompassing various fuels and three different axial positions in the high-rise, multi-level, multi-compartment facility. At that time, each HDR fire test series was accompanied by extensive efforts to evaluate the predictive capabilities of a variety of fire models and codes developed in different countries by both blind pre-test and open post-test computations. A quite large number of open issues remained in the area of fire computer code predictive qualities upon completion of the HDR program. In the meantime, large progress has been made in improving and consolidating fire models and computer codes of all levels of simulations. This progress merits revisiting both experimental results and fire computer code validations. The results of the research efforts for this grant during FY 1996/97 are documented in two separate volumes. Volume 1: Test Series Description Report for T51 Gas Fire Test Series.
