| dc.description.abstract | © 2016 Elsevier Ltd 18 helically corrugated tubes with different geometrical configurations for exhaust gas heat exchangers are investigated in this study. Experiments are carried out with air flow on the tube side, cooled by a secondary water flow. The dimensionless corrugation pitch p/di varies from 0.27 to 1.53, the dimensionless corrugation height e/di from 0.02 to 0.056, and the corrugation angle φ from 9.2° to 37.0°. To match the typical range of exhaust gas heat exchangers, the examined Reynolds number range is 5000<Re<23,000. Nusselt number and friction factor are correlated with a power law of the corrugation dimensions. Furthermore, the thermal performance of the tubes is examined. It is shown that the highest thermal performance is achieved by a single-start corrugated tube with p/di=0.517 and e/di=0.040. Finally, suggestions are made, how to handle different manufacturing constraints for additional optimization purposes. | - |
