CDFR — Diagrid Hydraulic Analysis Using the Phoenics Code
The PHOENICS code has been used to simulate the complex flow patterns in the diagrid region of a proposed CDFR design of fast reactor. The computer model is being used to complement experimental investigations using a reduced-scale water model, from which the first data are expected shortly.
The initial PHOENICS predictions appear credible, and some preliminary parameter studies of model inputs have been performed to establish the sensitivity of the predictions, whilst validation data is awaited.
