Resumo: | Tire pyrolysis oil (TPO) shows promise as alternative fuels, not only for the raw material from which they can be produced (waste tires), but also their physical characteristics. In this work, the atomisation quality of TPO and its blends with diesel oil was evaluated from a statistical perspective. A 35 kW Y-jet atomiser, operating at an air-fuel mass ratio (AFR) in the range of 0.075 to 0.150, was used to produce the fuel sprays. The Log-Normal density function was used to describe the droplet size distribution of the sprays. Additionally, the d2-law was integrated into the density function to simulate TPO spray evaporation. The results showed that the increase in TPO in the fuel blend decreased the uniformity of droplet sizes in the spray, as well as increased the presence of larger droplets. However, operating the atomiser at a AFR = 0.150 reduced the presence of larger droplets and increased the volume fractions of smaller droplets. |
