In this project a TEG based WHRS
is optimized for auto-mobile applications.
To optimize the WHRS, the thermal
impedance of the TEG has to be
matched with the thermal impedance of
the heat exchanger used to transfer the
heat from the car engine exhaust gas to
the TEG and the thermal impedance of
the heat sink of the system.
The optimization procedure was based
on an analytical model. The analytical
model was tried to be validated by a
CFD model and experimental work.
The thermal resistance prediction of the
analytical model was found to be valid,
however the TEG module performance
was not.
The obtained optimal design was simulated
in order to determine the feasibility
of the WHRS.
