dc.description.abstractThis research uses computational methods to examine steady-state turbulent forced convection flow in a duct having rectangular cross-section equipped with flow-inclined baffles on the bottom wall. The aim of this study is to provide information about turbulent convective heat transfer in ducts with a roughened surface. Especially, it is intended to obtain the influence of newly designed baffles on convective heat transfer in detail. Between 1000 and 10,000, the Reynolds number is varied. The duct's hydraulic diameter is 75 mm. Air is used as the working fluid. Numerical calculations have been carried out using Ansys Fluent R18 commercial code. Governing equations have been solved iteratively. SST k-omega turbulence model has been used for solving turbulence equation. New engineering correlations have been gained from numerical calculations. In terms of the thermal enhancement factor, a number of different baffle inclination angles have been evaluated in comparison with both one another and a smooth duct. The results show that a steeper inclination angle of the baffle improves the heat transmission. Pressure drop also rises as the baffle inclination angles become steeper. In all situations, the greatest thermal augmentation factor is obtained at an inclination angle of beta = 0.41 rad, while the least is obtained at an inclination angle of beta = 0 rad.en_US
