By comparing the empirical and predicted performance diagrams of the composite solid propellants, it appears that there is a discrepancy between these two graphs .This deviation has been attributed to spatial burning rate variation which is related to burning rate fluctuation or hump effect. The most important reasons for this spatial burning rate variation are casting process. In order to appr...

Investigation shows that the some complex and expanded parameters are effective on the burning rate. In this paper we evaluate the effect of particles dispersion, size of AP particle, the size of Al particles, Fe2O3, viscosity, shape factor, the size of mixer and the mechanical parameters such as tensile and stress on the burning rate. These studies show that the decrease of AP particles, size ...

The influence of the initial fuel temperature on the burning behavior of n-heptane pool fire was experimentally studied at the State Key Laboratory of Fire Science (SKLFS) large test hall. Circular pool fires with diameters of 100mm, 141 mm, and 200 mm were considered with initial fuel temperatures ranging from 290 K to 363 K. Burning rate and temperature distributions in fuel and vessel wall w...

Although a many studies concerning crop residue burning have been conducted, the influence of crop residue burning on local PM2.5 concentrations remains unclear. The number of crop residue burning spots was the highest in Heilongjiang province and we extracted crop residue burning spots for this region using MOD14A1 (Thermal Anomalies & Fire Daily L3 Global 1 km) data and national land cover da...
