Abstract

Tubercles are a bio-inspired geometry of a humpback whale and its swimming behavior, several studies has revealed that tubercles at leading have significant role to control flow separation in incompressible flow. So these tubercles can be used as flow separation control devices. Present research work aim to analyze the aerodynamic performance of the tubercles Leading Edge (LE) aircraft wing at 30 angle of attack under transonic flow conditions. Aerodynamic performance of TLE wing were compared with baseline model i.e. (SLE wing) model. Numerical fluid flow analysis were performed through solving RANS by using finite volume method. The current study is performed at Reynolds = 3x106, and Mach no 0.8 where flow is considered compressible in transonic regime. To comprise the flow physics of problem, the figures are plotted to represent the lift/drag ratio for both straight leading-edge wing and leading edge tubercle wing. In this research it is concluded that unlike subsonic flow the leading edge tubercle does not offer better performance at 3 degree angle of attack in transonic flow regime. The maximum decline of 4.5% was observed in tubercles leading edge wing.
