We study the aerodynamics of a blunt-based body with rear flexibly-hinged rigid flaps, subject to turbulent flow Reynolds number Re=12000, under aligned and cross conditions yaw angle β=0° β=4°. To that aim, different values equivalent torsional stiffness are considered, cover range reduced velocity U∗=(0,3.48] in water tank experiments. The effect angular deflection plates on drag near wake is analyzed, experimentally numerically. results show that, U∗ herein undergo an inwards...
We investigate the quasi-static reconfiguration of rear parallel flexible plates on drag coefficient a blunt body. The coefficient, deformation, and main features turbulent wake are characterized experimentally in towing tank. It is found that increasing flexibility leads to an important reduction, induced by progressive streamlining trailing edge due deformation. study Vogel exponent adopted here evaluate limit potential reduction at large values Cauchy number, which shown be mainly caused...
We have conducted an experimental study on the use of rear flexible vertical flaps as adaptive solutions to reduce drag a squareback Ahmed body, and fluid–structure interaction mechanisms at turbulent wake. To that aim, wind tunnel experiments were compare performance various configurations including baseline body with rigid flaps. These tested under different aligned cross-flow conditions. The results reveal devices effectively within for low values dimensionless stiffness quantified...
