Abstract
The addition of nanomaterials to base liquid fuels for the enhancement of combustion properties has long generated interest, since it is linked to improvement in combustion properties in petroleum-derived fuels. This work investigates the effect of acetylene black nanoparticles on soy-based biodiesel and petrodiesel. These nanoparticles were added in various proportions to base fuels to make suspensions. Sub-millimeter-sized spherical droplets of such suspensions were ignited using hot wire loops, and the combustion process was recorded using a high-speed camera. An infrared imaging camera was also used to record the droplet combustion process. Properties such as ignition delay, combustion rate, total combustion time, flame stand-off ratio, and droplet temperature were measured with post-processing of the resulting images. The results showed an increase in ignition delay of up to 10% in biodiesel and up to 8% in petrodiesel. An up to 13% decrease in biodiesel combustion rate and 1.5% decrease in diesel combustion rate was also observed. Moreover, a maximum of 14% decrease in the total combustion time of biodiesel was observed, compared to a 13% decrease in that of petrodiesel. The results are expected to spark further interest in the exploration of acetylene black as an additive for other liquid fuels.
