Abstract
A numerical study turbulent airflow in the presence of transverse baffles was conducted. Two different types of baffles flat rectangular and trapezoidal, arranged in overlapping in a pipe of rectangular section is presented in this article. The governing equations based on k - ε model at low Reynolds number used to describe the turbulence phenomena, are solved by the finite volume method using the algorithm SIMPLEC. The velocity profiles were obtained for all the geometry considered and selected for different sections, namely, upstream, downstream and between the two baffles and the friction coefficients were obtained for different sections and for different Reynolds numbers.
