Sr Research Engineer
Working under general direction, the engineer will develop state-of-the-art computational models of a space experiment and perform model validation studies against unique microgravity and 1g experimental data. This is a key engineering research position within the Case Western Reserve University computational fluid dynamics (CFD) team responsible for the NASA funded Zero-Boil-Off Tank (ZBOT) Microgravity Experiments. The engineer is expected to perform most assignments independently by applying advanced computational methods to carryout high-fidelity, two-phase flow and heat transfer analyses. The ZBOT experiments are a series of International Space Station science experiments geared towards studying phase change and two phase flow and heat transfer in an enclosed Dewar during self-pressurization and pressure control in microgravity. The first experiment, ZBOT-1, Flew in 2017 the second experiment, ZBOT-NC, is scheduled to fly aboard International Space Station in December 2023. Specifically, the engineer will get started by working with existing state-of-the-art two phase CFD models developed during the ZBOT-1 project and then quite rapidly advance to plan, formulate and develop new CFD models for non-condensable gas effects and tank filling and droplet-spray charge-hold-vent chill down processes for ZBOT-2 and ZBOT-3 experiments. The two–phase CFD models will be developed independently by the candidate but through interaction with the principal investigator and others CFD experts on the university science team.
