Assessment of the influence of the physico-chemical properties of biomineral fuel mixtures on the characteristics of injection and spraying

The paper examines the influence of the physico-chemical properties of biomineral fuel mixtures (BMFM) on the injection and spraying characteristics, as well as on the processes of mixture formation and mixed fuels combustion. The characteristics under consideration depend on the density, kinematic viscosity and surface tension forces. The droplet diameter and length of the injected fuel jet are directly dependent on the kinematic viscosity, and the spraying angle is inversely dependent. Dependences by A.S. Lyshevsky and N.F. Razleytsev form the basis for developing an analytical model. According to the results obtained in computation, the paper establishes that alteration in the injection time is 0.88 and 0.71, droplet diameter - 1.06 and 1.17, and atomization angle - 0.95 and 0.86 for BMFM-10 and BMFM-25 in relation to the diesel fuel, respectively. An additional research result is the improved method for determining the injection and spraying characteristics of the biomineral fuel mixtures.
