Flow turbulization is one of the most commonly used techniques for improving heat transfer. This study uses numerical simulation and experimental tests to examine ball turbulators' effect on fluid friction and heat transfer characteristics in a circular pipe. Ball turbulators with different diameters of 10, 15, and 20 mm and spacer lengths of 20 cm are inserted in the circular pipes. The ratio of the diameter of the ball to the diameter of the internal flow path of the pipe, ball turbulent ratio (BTR) =D_b/D_p, becomes 0.41, 0.62, and 0.83. The water was a working fluid with Reynolds numbers 3,500 to 11,500. The findings demonstrate excellent agreement with deviations of less than 11%. The maximum thermal performance factor reached about 1.18, 1.24, and 1.4 for the BTR 0.41, 0.62, and 0.83, respectively. The ball turbulators increase friction factor; this increase in experimental findings is 52, 65, and 78% at BTR 0.41, 0.62, and 0.83, respectively. Also, it is noticeable that there is a gradual decrease in thermal performance when the Reynolds number range is higher than 7500.
