火星大气环境模拟装置设计及仿真分析研究

摘要

对火星表面大气环境特性进行了研究,通过选取合适的计算方法并结合FLUENT流体有限元计算软件对火星表面稀薄气体内部环流进行了模拟仿真分析,提出了以动量源模拟风扇段内流的仿真方法,并进行了可行性讨论.进一步实现了针对圆柱形模拟装置多工况下的内部气体流场稳态和非稳态计算仿真,并对计算结果进行了分析讨论,为火星大气环境模拟装置的设计提供了技术支持和参考.%The characteristics of Martian atmosphere were studied.A simulation calculation module of the Martian atmosphere simulation environment box was set up by choosing appropriate calculation method combined with FLUENT fluid finite element calculation software.The module realizes steady and unsteady calculation simulation of interior flow field under multiple working conditions of the cylindrical Martian atmosphere environment simulation devices.The calculation results was analyzed so as to provide technical support and reference for design of the Martian atmosphere environment simulation device.
