Costa, "The influence of aluminium particles in a Hydroprocessed Vegetable Oil combustion", ECM-2021 - 10th European Combustion Meeting, Napoli, Italia, 14-15 April, 2021http://hdl.handle.net/10400.6/12571The present work experimentally investigates single droplet combustion to understand the effect of aluminum particles when added to a biofuel. Experiments are carried out in a drop tube furnace to evaluate the influence of size and concentration of the aluminum particles. Two different sizes (40 nm and 5 μm) and two concentrations (0.5 and 1.0 wt.%) are studied at 1000 °C. The addition of aluminum particles improves biofuel combustion. Decreasing the particle size and increasing the particle concentration leads to a significant enhancement in the burning rate compared to the pure HVO. Micro-explosions are detected at the end of droplet lifetime when particles are added to biofuel.engDroplet combustionHVO biofuelAluminum particleBurning ratemicro-explosionsconference object
