Abstract To address the problem that energy capture efficiencies of existing flapping airfoil power generators are lower than those traditional turbine generators, a dual‐layer structure was adopted to improve performance semiactive airfoil, inspired by multiwing flying mode dragonflies in nature. The influence on systematically analyzed Taguchi experimental design and computational fluid dynam...

Placing cylindrical vortex generators (VGs) at the base of a uniform micro-channel heat sink (MCHS) enhances transfer, but incurs substantial pressure drop. The effect different VG parameters, including position (front, middle or back), radius (R) in range (100–300) μm and distance (D) between them (0–500) are considered to enhance conjugate transfer. Laminar flow flux conditions relevant micro...
