The baffles were of the zig-zag type or plane one. The calculations are based on the finite volume approach and the average Navier–Stokes equations along with the energy equation, have been solved using the SIMPLE algorithm. The nonuniform structured quadrilateral-type element mesh is used in this study. The fluid flow patterns represented for Reynolds numbers based on the hydraulic diameter of the channel ranging from 5000 to 20 000. Effects of various Reynolds number values on flow fields, dimensionless axial velocity profiles, as well as local and average friction coefficients in the test channel is presented. The obtained results show that the flow structure is characterized by strong deformations and large recirculation regions. In general, the fluid velocity and skin friction loss rise with the increase in the flow rate and hence the Reynolds number.}, type={Article}, title={Simulation and numerical analysis of a rectangular pipe with transversal baffle – comparison between zigzag and plane baffles}, URL={http://journals.pan.pl/Content/118909/PDF/art13.pdf}, doi={10.24425/ather.2020.135988}, keywords={Dynamic simulation, turbulent flow, Forced convection, Rectangular pipe, Baffle}, }
