Measurement and analysis of surface tension of B/JP-10 high-energy nanofluid fuels for enhanced heat transfer in combustion

The surface tension of a liquid fuel is an important parameter in the fuel atomization process. B/JP-10 nanofluid fuels with different particle concentrations (5 mass%, 10 mass%, 15 mass% and 20 mass%) were prepared by selecting 100 nm, 300 nm and 500 nm B particles by a two-step method, in which Tween-85 was used as a surfactant. The surface tension of the above nanofluid fuels was tested at different temperatures (10-90 celcius) using the platinum plate method to investigate the effects of surfactant, temperature, particle concentration and temperature on the surface tension of B/JP-10 nanofluid fuels. The results show that the addition of surfactants helps to reduce the surface tension of the nanofluid fuel. The surface tension of the nanofluid fuel is higher than that of pure JP-10 and increases with increasing particle concentration and decreases with increasing particle size. The surface tension of the suspended fuel decreases linearly with increasing temperature in a certain temperature range (10-60 degrees C).

Automated summary

This study investigates the effects of surfactant, temperature, particle concentration and particle size on the surface tension of B/JP-10 nanofluid fuels. The results show that the addition of surfactants helps to reduce the surface tension of the nanofluid fuel, while the surface tension is higher than that of pure JP-10 and increases with increasing particle concentration and decreases with increasing particle size. The surface tension of the suspended fuel decreases linearly with increasing temperature in a certain temperature range (10-60 degrees C).
