Slope Dependent Turbulence over Two-dimensional Wavy Surfaces
Balaji Jayaraman, Saadbin Khan
Knowledge of turbulent flows over non-flat surfaces is of major practical interest in diverse applications. Significant work continues to be reported in the roughness regime at hig…
Modification of Turbulent Boundary Layer Coherent Structures with Drag Reducing Polymer Solution
Yasaman Farsiani, Zeeshan Saeed, Balaji Jayaraman +1
The modification of dominant coherent structures that extend through the log-region of a drag reduced turbulent boundary layer is studied via examination of two-point correlations…
Quad-rotor Flight Simulation in Realistic Atmospheric Conditions
Behdad Davoudi, Ehsan Taheri, Karthik Duraisamy +2
In trajectory planning and control design for unmanned air vehicles, highly simplified models are typically used to represent the vehicle dynamics and the operating environment. Th…
On the Trajectory Dependence of Atmospheric Boundary Layer Turbulence Sensing using Small Unmanned Vehicles
Balaji Jayaraman, Sam Allison, He Bai
Atmospheric turbulence, especially in the near-surface boundary layer is known to be under-sampled due to the need to capture a wide separation in length and time-scales and limita…
Characterization of a Canonical Helicopter Hub Wake
Christopher E. Petrin, Balaji Jayaraman, Brian R. Elbing
The current study investigates the long-age wake behind rotating helicopter hub models composed of geometrically simple, canonical bluff body shapes. The models consisted of a 4-ar…
The Surprising Transition in Atmospheric Boundary Layer Turbulence Structure from Neutral to Moderately Convective Stability States and Mechanisms Underlying Large-scale Rolls
Balaji Jayaraman, James G. Brasseur
The vectoral wind structure of daytime atmospheric boundary layer (ABL) turbulence is strongly dependent on the balance between shear-driven turbulence production of horizontal flu…
