Vehicle Exhaust Waste Heat Recovery Model with Integrated Thermal Load Leveling

reportActive / Technical Report | Accession Number: ADA621191 | Open PDF

Abstract:

A system-level model describing thermoelectric generator TEG-based vehicle engine exhaust waste heat recovery WHR is formulated, and the impact of using high effective thermal conductivity devices to spatially load level the hot side of the TEG array is evaluated. Because TEG material properties are extremely sensitive to temperature, load levelled WHR systems generate more power at a higher efficiency than traditional WHR systems. The importance of proper assumptions and accurate boundary conditions is highlighted, and directions for future research are identified
