... delayed detached eddy simulation and analyzed by dynamic mode decomposition. Findings The sampling point close to the conjunction of spike and blunt body and reattachment point represent complex frequency characters. More frequency components and modes are extracted with Reynolds number increasing...

... radius. The experiments were performed in Universiti Teknologi Malaysia wind tunnel sized of 2 × 1.5 m² test section with maximum speeds of 80 m/s. To investigate the effects of leading-edge radius, Reynolds number and angle of attack, the experiments were carried out at 1 × 10⁶...

... coefficient conservatively for the same free stream conditions. With increase in Reynolds number, lift coefficient and aerodynamic performance improved significantly for un-tripped aerofoil when stall angle is approached when compared to tripped aerofoil. Practical implications This study demonstrated...

... and Reynolds number are determined as important wing design parameters. Most important parameters over these parameters are determined using Taguchi method. The lift-to-drag ratio (CL/CD ratio) is chosen as the performance criterion and L8 orthogonal index is chosen as experimental study scheme for this study...
