摘要 | The flow characteristics of helium at low temperature are vital for designing a large-scale helium cryogenic system, which is a key component of the scientific apparatus. However, it is difficult to measure the flow resistance characteristics of helium at low temperature experimentally, so the empirical formulas under room temperature are often used. In order to study the applicability of empirical formulas under low temperature conditions, several models of horizontal straight tubes, vertical straight tubes, 90° circular elbows, diffusing tubes and reducing tubes are established by using commercial software FLUENT. Compared with the empirical formula, the flow resistance calculated by the straight-line simulation has a little difference which is less than 10%. The difference of that between the horizontal tubes and the vertical tubes is less than 1%. The simulation results of the flow resistances of the 90°circular elbows are quite different from the empirical formula. The empirical formula of the sudden expansion tube is close to the simulation result of 60-degree diffusing tube. The error between the empirical formula of the reducing tube and the simulation result is small. © Zhejiang University Press. 2023. |
