Among the major problems in the use of baffles in heat exchangers is the formation of hot points due to the stagnation of the flow behind baffles. The present work shows a design of a porous space in the baffles in order to shake the dead zones behind these baffles. The numerical investigation is based on the Navier Stocks averaged (RANS) using FLUENT software. The results validated by experimental data from the literature shows that the porous space presented in this paper reduces in an observable manner the hot points and increase the heat transfer rate.
