Abstract Details

2011, Master of Science, Ohio State University, Mechanical Engineering.
A zero-dimensional fluid and thermodynamic model of an engine, cooling system, and exhaust system was developed in order to simulate the operation of an advanced thermal management system. The model was calibrated with experimental data where available. The thermal management system modeled in this work employed waste heat recovery to reduce engine, coolant, and lubricating fluid warm-up times and fuel consumption following a cold-start. The model was used to develop a control strategy for two valves in the exhaust system which control the flow of exhaust through an exhaust-to-coolant heat exchanger. The objective of the controller was to minimize coolant warm-up time without violating any of the system constraints. A model-based open-loop controller was developed that was able to reduce warm-up time by nearly 35% on the FTP city drive cycle while respecting the limitations of the system.
