Impact of the formation angle on the drag of bio-inspired -formations
Prasoon Suchandra, Shabnam Raayai-Ardakani
Bio-inspired flight formation is a well known technique for energy saving among groups of fixed-wing aircraft, and as of recently, for groups of quad-rotors. Here, we s…
Localized performance of riblets with curved cross-sectional profiles in boundary layers past finite length bodies
Shuangjiu Fu, Shabnam Raayai-Ardakani
Riblets are a well-known passive drag reduction technique with the potential for as much as 9% reduction in the frictional drag force in laboratory settings, and proven benefits fo…
Impact of bio-inspired V-formation on flow past arrangements of non-lifting objects
Prasoon Suchandra, Shabnam Raayai-Ardakani
Inspired by the energy-saving character of group motion, great interest is directed toward the design of efficient swarming strategies for groups of unmanned aerial/underwater vehi…
Double-light-sheet, Consecutive-overlapping Particle Image Velocimetry for the Study of Boundary Layers past Opaque Objects
Shuangjiu Fu, Shabnam Raayai-Ardakani
Investigation of external flows past arbitrary objects requires access to the information in the boundary layer and the inviscid flow to paint a full picture of their characteristi…
A Polynomial Framework for Design of Drag Reducing Periodic Two-dimensional Textured Surfaces
Shabnam Raayai-Ardakani
Periodic and symmetric two-dimensional textures with various cross-sectional profiles have been employed to improve and optimize the physical response of the surfaces such as drag…
Capturing Strain Stiffening Using Volume Controlled Cavity Expansion
Shabnam Raayai-Ardakani, Tal Cohen
Strain-stiffening is a well-documented behavior in soft biological materials such as liver and brain tissue. Measuring and characterizing this nonlinear response, which is commonly…
