ATOMIZATION OF SHORT–CHAIN TRIGLYCERIDES AND A LOW MOLECULAR WEIGHT VEGETABLE OIL ANALOGUE IN DI DIESEL ENGINESPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Transactions of the ASABE. Vol. 46(4): 955–958 . @2003Authors: D. P. Geller, J. W. Goodrum, E. A. Siesel Keywords: Atomization, Biodiesel, Cuphea, Density, Methyl ester, Short–chain triglycerides, Surface tension, Triglycerides, Vegetable oils, Viscosity To aid in the development of chemical composition models for diesel fuel substitutes based on vegetable oils and their derivatives, atomization properties of pure short–chain triglycerides were studied using a TK Solver and a previously developed model. The atomization of a simulated low molecular weight oil from the plant Cuphea VS–320 was also analyzed. This analysis required the measurement of density and surface tension for this oil, which are presented here. The atomization properties were compared to those of peanut oil, peanut oil methyl ester, and diesel fuel to provide reference. The low molecular weight triglycerides and simulated Cuphea oil exhibited atomization properties between those of standard No. 2 diesel fuel and more common vegetable oils such as peanut oil. This suggests better fuel performance with short–chain oils and triglycerides than with traditional vegetable oils containing predominantly long–chain triglycerides. |
