摘要
This paper reports the experimental study and theoretical analysis of the internal circu-lation among horizontal heated tube bundles. In the experiment the velocity and temperaturedistributions of the single phase liquid in the bundles are measured. A 2-D numerical analy-sis method to simulate the internal circulation among the heated tube bundles is developed.The calculation of the velocities at the internal boundary points, that is, at the walls of thetube bundles, is carried out successfully by setting the source term in the momentum equa-tions as desired values. The calculated results are in good agreement with the experimentaldata.
