In this study, steady-state forced convection heat transfer and pressure drop characteristics for hydrodynamically fully developed thermally developing three-dimensional turbulent flow in a horizontal smooth trapezoidal duct with corner angle of 75 and hydraulic diameter of 0.043 m were both experimentally and numerically investigated in the Reynolds number range from 2.6 x 103 to 67 x 103 for isothermal conditions. Results have shown that there is a good agreement between the present experimental and numerical results.
