Abstract

To cool the internal passage of a trailing edge, a cooling method that uses a pin-fin array, perforated blockage, and an angled rib is applied. This study investigated the effect of an angled rib in a pin-fin array combined with perforated blockage. A numerical analysis was conducted to analyze the flow and heat transfer characteristics of each shape by changing the rib angle to -45°, 0°, and 45°. The Reynolds number based on the pin diameter was fixed at 5,000. The influence of the flow distribution on the channel confirmed the heat transfer and pressure characteristics. As a result, the flow distribution in the channel was different depending on the rib angle. In particular, when the perforated blockage was combined with the pin-fin array, the uniformity of the heat transfer was improved.
