Abstract: “Entropy generation of fully developed turbulent flow in a transition duct is investigation in this study. Air was used to study as working flow on entropy generation, flow passing from a rectangular to square channel in turbulent flow conditions, experimentally. Entropy generation was increased according to the equivalent conical angle of the transition duct. The lateral side angle of the duct was varied to investigate its effect on the entropy generation.”
