Assessment of heat transfer in a triangular duct with different configurations of ribs using computational fluid dynamics
Numerical investigation was performed to improve heat transfer in triangular ducts using ribs of different sizes and shapes. Increased heat transfer may be achieved by the roughness in the duct surface, which is a prospective and successful method. It is shown that the sectional shape of the roughne...

| description | Numerical investigation was performed to improve heat transfer in triangular ducts using ribs of different sizes and shapes. Increased heat transfer may be achieved by the roughness in the duct surface, which is a prospective and successful method. It is shown that the sectional shape of the roughness given on the area exposed to heat has a major impact on the effective performance of heat transfer channels. This research will study the results of using different shapes and sizes of roughness components, such as triangular rib (e/W = 0.1, 0.2, and 0.3) as well as semi-circular rib (R/W = 0.1, 0.2, and 0.3). Likewise, the influence of rib width b (b/w = 0.2, 0.4, and 0.6) is examined using computational fluid dynamics for variable Reynolds number (1,000 < Re < 1,800) at fix rib height (e/W, R/W = 0.1). ANSYS FLUENT 2020 R1 is used to model the heat and the flow dynamics in roughened ducts. The best performance was for the semi-circular ribs. At a Reynolds number of 1,200, the optimum ratio of enhancement (ε) for the semi-circular rib sample e = 0.2 × W was 1.717. Additionally, sample 4 has the greatest Nusselt number across all Reynolds numbers and is the best-shaped sample. Furthermore, the pressure drop and the friction factor also increase when the rib width is increased, the sample (p = 0.2 × W) highest pressure drop and coefficient of friction values. |
