Abstract

This paper presents numerical investigation results of airflow through a square duct with an installed tripping rod. A square section duct with a hydraulic diameter of 125 mm was built for this study. This duct consists of straight duct at upstream and downstream also square elbow 90° with curvature ratio (R/Dh=3). Tripping rod is installed on a square elbow (90°) with three variations on shapes. These shapes are circular cylinder, square cylinder, and oriented square cylinder, respectively. All tripping rod has a constant dimension based on circular cylinder diameter. Tripping rods are located near the inner wall of a square elbow with a constant gap ratio of (g/d) 0.2. The turbulent viscous models are used to simulate with a k-epsilon standard with enhanced wall treatment. All simulations are modeled for Re 1.59 × 10⁴ based on the hydraulic diameter of the duct. The numerical simulation result is consists of turbulent intensity and pressure drop. There is a reduction of downstream pressure drop based on the result if the circular cylinder used as the comparison point, as follows oriented square cylinder has 2.23 % reduction. square cylinder has 1.74 % reduction at downstream at 8°.
