Thesis Student Propulsion

TL;DR

Thesis Student Propulsion: Developing and validating a second-iteration heat exchanger for a tank pressurization system using waste engine heat, with an accent on reduced-order system modeling, experimental data validation, and optimizing heat exchanger geometry. Focus on analyzing heat exchanger dynamics (including start-up transients), estimating soot deposition effects, and defining parameters for temperature control of pressurization helium.
