Abstract
In this paper, the combustion characteristics of alumina nanoparticles dispersed jatropha biodiesel based nanofluids were investigated by dispersing the alumina nanoparticles having average size of ~13 nm in jatropha biodiesel with 0.1 volume fraction. Only longer duration having more than one year stable nanofluids were tested for the combustion characteristics such as evaporation time on a hot-plate test in the temperature range of 300 0 C to 600 0 C. The preliminary evaporation test results revealed that the evaporation time of one year older stable ~13 nm alumina nanoparticles dispersed nanofluids significantly improved and were comparable to that of the commercially available diesel fuel beyond 450 0 C. Such type of biofuel based nanofluids having longer term stability and improved combustion characteristics can be utilized directly as an alternate fuel for the future diesel engines.
