RÉSUMÉ

The shell-and-tube heat exchanger with a trefoil-hole baffle in the shell side is extensively used at nuclear power stations. In the present work, a periodic flow unit duct was taken as a simplified model to numerically investigate the thermal-hydraulic performance of the trefoil-hole baffle heat exchanger. Based on the numerical results, the empirical correlations for the Nusselt number and pressure drop were derived, and the relative errors of the two empirical correlations are all less than 10%. The detailed characteristics of fluid flow and heat transfer for the fully developed section in the shell side of the trefoil-hole heat exchanger were analyzed. The fluid flow experiments for the trefoil-hole baffle heat exchanger were carried out. The flow velocities at special points in the shell side of a heat exchanger were measured by using a Laser Doppler Velocimeter (LDV). It can be concluded that the relative errors of the axial velocity Vz for all measured points between simulation and experiment are within 20%. The validity and accuracy of the numerical simulation results are verified.
