Validation of special nodalisation features for lumped-parameter injection modelling based on MISTRA facility tests from ISP-47 and SARNET

The paper presents results of the simulation of two MISTRA facility experiments - M5 from the SARNET spray benchmark and one test from the International Standard Problem No. 47. Presented simulations were performed using lumped-parameter code COCOSYS with the same enhanced nodalisation scheme. Lumped-parameter code provided reasonable results in both cases. Nodalisational features employed to enhance plume injection simulation in lumped-parameter approach successfully mitigated inherent limitations of this approach in gas mixing modelling.
