Modeling of Iodine Feeding System to Achieve Flow Control under the Coupling of Multiple Conditions

The design of an iodine working medium storage and supply system is one the key technologies for electrical propulsion medium. Solid sublimates into a gaseous state in tank, transported to thruster through flow control components such as proportional valve or throttle tube. However, has corrosive properties poor thermal conductivity, which can easily cause condensation tube valve, affecting accuracy experimental results blocking pipeline, leading suspension experiment. Based on level modeling electric system, taking account impact coupling effects various conditions physical parameters vapor, tanks, pipelines, outlet conditions, valves mass rate achieved by adjusting opening comparative example, providing reference selection size future ground experiments opening.
