Computation of flow through a block assembly

A simple procedure is presented for computation of flow through gaps in the assembly block. This procedure enables estimation of bypass flows through the reflector of a gas cooled reactor. The method is based on a simplified channel network representation of the gap configuration. Using computer program the procedure was applied for verification on an experimental model. The results of the computation were in good agreement with the experimental data. A typical three dimensional model of a gas cooled reflector was also computed. (authors) 2 refs, 3 figs
