INFLUENCE OF AMBIENT TEMPERATURE ON PENDANT DROPLET EVAPORATION OF BIODIESEL BLENDS WITH NANOPARTICLES

In this study, the evaporation characteristics of biodiesel derived from waste cooking oil are blended with nanoparticles at elevated temperature and pressure. Experiments were carried out in a confined room with high ambient temperatures and humidity. In all of the trials, the temperature is kept at room temperature. Pure diesel and diesel with 50 ppm titanium oxide both evaporate at 80 degrees Celsius, while D100 with 50 ppm titanium oxide evaporates at a faster pace, in 11 minutes, at the same temperature. Similarly, when D100 and D90B10 with 50 ppm of TiO₂ are tested at a higher temperature, i.e., 100^◦C, it is obvious that D90B10 with 50 ppm of titanium oxide evaporates at a quicker pace, i.e., in 10 minutes, compared to D100 and D90B10 without titanium oxide. Diesel, on the other hand, took 12 minutes to evaporate at 100^◦C. The size of the droplets changes depending on the time of day and the temperature. During the course of the experiment, a change in droplet diameter was observed. When comparing the results of the two experiments, it can be seen that adding nanoparticles to the diesel has increased the evaporation rate when compared to using regular diesel (D100).
