Abstract

Abstract

In the problem of U-tube reverse flow, accurate determination of the critical point of reverse flow is quite important. In this paper, a theoretical analysis model of U-tube reverse flow characteristics was established, and the criticality criterion of reverse flow based on the theoretical analysis model was simplified. The calculation results of the theoretical analysis model and the simplified reverse flow critical criterion were compared with the experimental results. The results showed that the calculation results of the reverse flow theoretical analysis model and the simplified reverse flow critical criterion were in good agreement with the experimental results, and the absolute values of the average relative errors were 3.4% and 3.7%, respectively. It showed that the theoretical analysis model of reverse flow and the simplified reverse flow critical criterion were more accurate for the prediction results of reverse flow point.
