AB - The present paper highlights a computational analysis of air-flows around  rectangular and triangular turbulators inside baffled heat exchanger  channels in order to improve heat transfer between the fluid and their  heated areas. The dynamic and thermal fields as well as fluid temperature  curves at the outlet of the exchanger are studied. The computational study  is conducted by utilizing SIMPLE algorithm with FLUENT system based on the  finite volumes. The analysis clearly demonstrated the presence of highly  turbulent flows and the appearance of many vortices in various regions of  the exchanger. By comparing the different heat exchangers, it was found that  the baffled channel fitted with rectangular turbulators produced high fluid  temperature values at the channel outlet, indicating the significance of  using this rectangular form of turbulators in order to enhance the  interaction between the hot spaces and the used fluid.
