Radiative spectroscopy characterisation of participating media
Combined theoretical and experimental techniques are developed
to study light–matter interactions for participating media
encountered in high-temperature solar thermal and thermochemical
applications. The scope of research includes design and optimisation
of an experimental radiative spectroscopy/radiometry facility and
demonstrating its use to determine effective optical and radiative
properties of various participating media types
such as particle suspensions,
packed beds, nano-, micro- and macro-structures, fibrous media,
semi-transparent solids and liquids, and molecular gases.
Inverse radiative transfer models are developed to infer the radiative
and optical properties from measured overall characteristics such
as the transmittance, reflectance, and emittance.
