WITHDRAWN: GlennICE Simulation of Supercooled Water Droplet Ingestion Into the Honeywell Uncertified Research Engine (HURE)

Three-dimensional simulations of the Honeywell Uncertified Research Engine (HURE) using the NASA codes FUN3D and GlennICE have been carried out. The ability to prescribe a radial distribution of cloud conditions has recently been added to the GlennICE software. The present work compares simulation results with both uniform inlet cloud and a cloud with a radial inlet profile. The main objective is to demonstrate the current capabilities of the GlennICE software to analyze fan icing. The simulation undertaken, while qualitative, demonstrates the information that can be extracted, and the resources required. The study begins with a specific operating point used in an earlier experiment. Then several additional operating points are created by reducing the rotation rate of the fan while maintaining constant air mass flow. For each of the operating points a uniform cloud was introduced at the inlet. Then an additional simulation introduced a radial variation in the cloud at the inlet. The results highlight the progression from much of the cloud hitting the fan (and relatively little making it to the exit) when highly loaded to much less hitting the fan (and most making it through to the exit) as rotation rate is reduced. The initial radial cloud demonstration uses uniform water content in the center of the inlet with zero water content beyond a certain radius. The expected loss of water collection on the outer radius of the fan and exit are observed.
