Abstract:
Low Reynolds number aerodynamics is important for various applications including wind turbines and propellers, micro-aerial vehicles, sailplanes, leading edge control devices, high-altitude unmanned vehicles. These flows are generally characterized by the presence of laminar separation bubbles. These bubbles are generally unsteady and have a significant effect on the overall resulting aerodynamic forces. A computational study was done to investigate the behavior of unsteady wake disturbance on laminar separation bubble over blades in turbo machines. A cylindrical rod was used to produce unsteady wake as in the case of multistage turbo engines. The study of the effect of unsteady wake disturbance on laminar separation bubble is carried out over an Eppler-387 airfoil in 2-D, Various instantaneous aerodynamic parameters including pressure, lift and drag coefficients are calculated computationally by using CFD code FLUENT and GAMBIT.
