摘　　要：开展火星尘暴环境地面模拟实验来验证火星探测器的性能是至关重要的,因此须建立火星尘暴环境的地面模拟装置。本文在对国外火星尘暴和气动模拟设备及其技术特点分析的基础上,提出了采用二次风输送的高速火星尘暴模拟系统总体方案,进行了高速火星尘暴气力输送流程的设计,并给出了沙尘质量流量、输送混合比、输送速度、输送压力、管道直径以及二次风量等气力输送参数的算式。本文研究成果可为我国的高速火星尘暴模拟装置工程设计及实施提供参考。We reported the design optimization of pneumatic conveying system,a subproject of the high-speed Martian dust-storm wind-tunnel,which simulates the realistic Martian environment for evaluation of China’s Mars probe.The original work was the secondary wind injection proposal,in which the primary nozzle injects a mixture of CO2 and dust;the secondary nozzle-array injects CO2 only for triple purposes:including further increasing flow-rate,initiating well-defined circulating dusty wind and minimizing turbulence in wind tunnel.The major variables,including but not limited to the conveying pressure/mixing-ratio/speed,mass flow-rate,pipe-diameter and secondary air volume,were optimized via extensive literature search,by experimental data analysis,in numerical simulation and in theoretical calculation.We suggested that the design optimization of pneumatic conveying system be of some basic and technological interest for the development of China’s high-speed Martian dust storm simulator.
