中文摘要:采用Mixture多相流模型、Realizable湍流模型与SIMPLEC算法,应用CFD软件Fluent对内混式自吸泵自吸过程的气液两相流进行了数值模拟。通过分析不同含气率条件下流场的压力分布、速度分布、气相分布,探讨了气液两相介质在泵内的运动情况,一定程度上揭示了内混式自吸泵自吸过程的内部流场变化规律,为自吸泵的设计提供更多的参考依据。

Abstract:3-D simulation was performed for the gas-liquid two-phase turbulent flow in self-priming pump by using Fluent software with Mixture model, SIMPLEC algorithm and Realizable turbulence model. The gas-liquid two-phase flow in self-priming pump was investigated in the pressure in the pump, the velocity in the pump, the distribution of gas and liquid phase in the pump. To some extent, the results reveal the self-suction process of the two-phase flow in self-priming pump, and provide references for self-priming pump design.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
