Simulation study on cooling potential of multi-tube earth-air tunnels.

[In Chinese. / En chinois.]

Author(s) : SONG L., ZHU Y.

Type of article: Article

Summary

Based on a 3-D unsteady heat conducting mode and a 1-D liquid heat transfer mode, this paper establishes the heat transfer mode of multi-tube earth-air tunnel by using the finite difference method. It verifies the correctness of this mode by a comparison between simulated and test data. It develops a simplified method with a modified temperature and it analyses the influences of tube number, depth of buried tube and tube spacing on cooling potential of multi-tube earth-air tunnels.
