Abstract: A direct, single-shot, non-intrusive planar temperature measurement of micron-sized particles in an unsteady flow has been demonstrated. Particles of diameters between 10µm and 50µm were fluidised using an optically-accessible fluidised bed system. The particle temperature was measured with a single ICCD camera fitted with an image splitter and filters to simultaneously record two images over a 7.5mm × 10.8mm area. This resulted in particle temperature maps of 51 pixels/mm, with an average of 15 particles in the measurement region at any given time. The particles were heated to temperatures up to 350°C with solid-state solar thermal simulator to generate a highly uniform heating region at fluxes of up to 21.1 MW/m². These fluxes exceed the range typically found in the particle receivers in Concentrated Solar Thermal (CST) systems, demonstrating that the method is more suitable for investigating heat transfer in them.
