Aerodynamic load evaluation on a highly flexible wing by Lagrangian Particle Tracking

The technical advancements achieved during the last decade have permitted the implementation of low-fidelity numerical methods to analyze simplified aeroelastic problems. However, the available computational power is still incapable of dealing with more realistic events involving complex structural dynamics and flow regimes. For this reason,...

Rotating Discs for Turbulent Drag Reduction: An Experimental Study

The reduction of turbulent skin-friction drag has the potential to generate numerous societal benefits. In large-scale industrial applications, the largest share of energy consumption goes into overcoming the friction drag produced by turbulent boundary layers formed on the outside wall. Estimates assess that over 50% of the total fuel burn is...

Experimental Investigation of Wheelhouse flow using PIV

Aerodynamics has become increasingly important these days in the design of automobiles due to the increased constraints placed on the emissions. In the past the focus has been primarily on the shaping of the upper body. However, due to practical requirements, further scope of improvements to the upper body has been greatly reduced. The focus has...

The Effect of Nozzle Length and Exhaust Plume on Transonic and Supersonic Axisymmetric Base Flows: An Experimental Study

A combined PIV and Schlieren measurements have been carried out in the transonic-supersonic wind tunnel (TST-27) to investigate the effect of exhaust plume and the variation in nozzle length on the flow topology and mean pressure distribution on the wake of axisymmetric backward facing step model at freestream Mach numbers of 0.76 and 2.20,...
