Experimental characterization of a turbulent round jet in support of validating the CFD code MODTURCCLAS
[en] Detailed predictions of moderator flow patterns and the associated temperature distributions in the calandria of CANDU reactors are required as part of safety analysis of certain accident scenarios. The specialized computational fluid dynamics (CFD) code MODTURCCLAS V2.9 1ST has been selected as the Canadian nuclear industry's tool for predicting moderator temperature distribution and flow patterns. The code requires extensive validation, which cannot be accomplished using only existing experimental data. To close gaps in the validation database, a program of three-dimensional moderator circulation experiments is being conducted for Ontario Power Generation Inc. (OPGI) at Chalk River Laboratories. The experimental program is divided into a separate-effects and component-testing stage, and a quarter-scale calandria model integral testing stage. One of the separate-effect tests consisted of a detailed characterization of a turbulent round jet in a confined tank. This paper presents the results of this test, and compares them with published results. The experimental results, in general, agree very well with published measurements and will be used in the validation of MODTURCCLAS. (author)
