Abstract:
Bio-inspired designs have been serving as a great inspiration for Aerodynamists for the past several decades. The biological features of each species have evolved through generations that play a substantial role in their ultimate survival. Manmade technologies have significantly benefited from these evolutionary attributes by mimicking such optimal features through artificial means of engineering. Biologically mimicking a particular feature of a natural species for scientific applications has introduced an interdisciplinary field of study that is popularly termed as “Biomimetics”. Biomimetic solutions have gained greater scope because of their unique potential to address the existing design challenges. The present review article approaches the state-of-the-art biomimetic techniques in a qualitative as well as quantitative perspective by mainly focusing on the potential aerodynamic applications. Through a quantitative approach, emerging researchers can have a firm basis from a pool of existing techniques. Drag reduction, lift enhancement, and flow separation control are the major design optimization challenges existing in the field of aerodynamics. The Biomimetic techniques discussed herein are evaluated on such qualities through consecutively organized sections which are the key instruments for non-flapping applications. A critical review on the well-liked biomimetic techniques for flow control is addressed with their potential applications in relevance to the aerospace industry. Few patented techniques from allied fields like hydrodynamics are also discussed because of their conceptual effectiveness in aerodynamic applications. Furthermore, the flow control effectiveness of Humpback Whale (HW) inspired biomimetic leading edge tubercles is numerically investigated with straight and sweptback wing configurations. The results clearly indicate the potentials of biomimetic techniques to transform the future designs of aerodynamic surfaces.
