Abstract: |
The physical stability of solid liquid mixed fuels is of great significance for the quality and safety of the fuel. The volatile liquid components caused by high temperature environments will have extremely complex effects on the physical stability of fuels. This article simulates and accelerates the changes in fuel physical stability through self designed experimental devices, and analyzes the role of high temperature factors based on the trends of liquid fuel precipitation and density distribution. The results indicate that the top of the fuel in a natural stacking state is greatly affected by saturated vapor pressure, while the middle and bottom form independent gas liquid equilibria. The wetting effect of liquid fuel on solids increases in high temperature environments, which is conducive to the adsorption of liquid components on solid particles. The solid liquid mixture fuel with a solid liquid volume ratio of 1.25∶1 and nitromethane accounting for 40% of the liquid component maintains the best physical stability under the temperature conditions of 303~333 K. |
