This article relates to work on numerical simulations supporting the experimental determination of the particle size distribution of liquid aluminium oxide droplets resulting from the combustion processes inside solid rocket motors. The droplets are sampled downstream from the fuel grain at a certain distance from the burning surface. This allows the large vortices present in the flow to divert mainly smaller droplets away from the sampling probe, leading to a systematic bias in favour of the larger particles. By adjusting the size distribution of the injected particles in the numerical simulations, the experimental results have been reproduced numerically. Under the assumption that the hypothesis underlying the numerical simulations are valid, this size distribution would directly correspond to the particle sizes as they emerge from the surface of the propellant.
