Abstract:
In view of the technology of nano-iron-based metal fuel engine, the particle combustion model and the nozzle two-phase flow control model were established in this study.Based on VC++ independent programming, the parameters in the nozzle of nano-iron-based metal fuel engine were analyzed, such as the particle phase velocity, particle temperature, particle size, mass transfer rate, particle velocity lag, temperature lag, fluid density, pressure, Reynolds number, Mach number, gas phase velocity, particle velocity, particle velocity lag and temperature lag.The important effects of 0.4-1.0 μm particle size and 10-40 iron oxide particles during the condensed phase on the two-phase flow loss of engine were mainly investigated.The results show that the changes of condensed phase content and particle size have significant effects on particle temperature lag and velocity lag.When the condensed phase content is approximately 30, the nano-iron-based metal fuel engine achieves the best specific impulse performance.This study can provide a theoretical reference for the optimal design of a new generation of nano-iron-based metal fuel engine.
