Abstract

The passive mode of heat transfer enhancement is most frequently used in the process heat transfer applications. The cross-flow heat exchanger prominently uses the circular tubes in forming an array of tube bank. however, the development of wake and high-pressure drop lowers the thermal performance of the heat exchanger. In this study the numerical analysis is performed over the camshaped tube to investigate the thermal performance of the system. The CFD results indicates that cam-shaped tube results in slight lower heat transfer rate over circular due to reduction in frontal area, but pressure drop is also significantly very low. This leads to the overall improvement in the thermal performance of the tubes. The results are also compared with the experimental finding with overall deviation was found to be less than 10%.
