Droplet combustion of blended fuels with alcohol and biodiesel/diesel in microgravity condition

Based on a drop tower built in the lab space, an environment of reduced gravity was employed to study the droplet combustion of multi-component fuels, specifically of diesel mixed with alcohol (methanol, ethanol, and 2-propanol) and biodiesel. The falling duration was about 0.68 s and was sufficient for complete burning of a droplet with a diameter as small as 0.5 mm that was suspended at the crossing point of two ultra-thin fibers with a...
