This study considers the effects of polydispersity of particles on thermodynamic and
hydrodynamic behaviour of solid particle solar receivers. To this end we consider a
canonical setting of a semi-periodic domain and perform DNS of turbulent flows interacting
with point particles subject to a heating source. The turbulent flow is seeded with
polydisperse particles that have a specific cumulative distribution function of particle sizes
that is tuned based on available measurements. A thermodynamically equivalent …
