Influences of high temperature factors on the physical stability of solid liquid mixed fuel
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.
