Computational Investigation of Drag Reduction by means of Two-Dimensional Roughness Element on the Suction Surface of an Airfoil
Abstract: Computational investigation carried out to the effects of a two-dimensional roughness element placed on the suction surface of a zero camber airfoil of 1 m chord on its performance is presented. The roughness element was placed on suction surface of the airfoil at a distance of 30% from the leading edge of the airfoil. The roughness element was in the form of a wire. The diameter of the wire was …

Optimizing Heat Transfer in Rectangular Channels with Turbulators: A Comprehensive Review
Abstract: Turbulators and various obstructions strategically placed along the airflow path in a channel are employed to enhance heat transfer This enhancement is achieved by disrupting the laminar sub-layer or intensifying turbulence within the duct passage. Numerous types of turbulator elements have been extensively utilized to optimize the heat transfer characteristics in such systems. Investigating further, researchers have explored the application of roughness elements in two-dimensional, three-dimensional, and irregular shapes. This …
