摘要
Abstract
In order to understand the gas-solid fluidization behavior on Mars,the computational particle fluid dynamics(CPFD)method was applied to analyze the fluidization phenomenon in the gas-solid fluidization bed reactor under different gravity conditions.The fluid velocity distribution characteristics in the gas-solid fluidized bed were studied,and the relationship between the pressure fluctuation of the bed and the environmental gravity and superficial fluidized gas velocity was obtained.The results showed that under the Martian environment,increasing superficial gas velocity could promote the formation of well-developed gas-solid fluidization,but the higher superficial gas velocity would increase the degree of disorder of the gas-solid flow field in the bed,which had a certain negative impact on the stable operating of the fluidized bed.The research results had certain guiding significance for future gas-solid fluidization operations used for on-site production of materials and energy on Mars.关键词
