A perspective on transonic buffet over an unswept finite wing

Magan Singh, Kartik Venkatraman

Transonic buffet is a well-known aerodynamic instability of shock/boundary layer interaction in the transonic regime for aircraft. So far, this phenomenon has typically been invest…

Probing Lithium Ion Transport at Individual Interfaces

Kartik Venkatraman, Yongqiang Cheng, Alexandra Moy +6

Ion transport across solid solid interfaces is often slower than through the bulk of a material, impeding the charge and discharge rate of batteries. Designing highly conductive in…

Sound induced by a simple impact oscillator

S. P. Narla, Kartik Venkatraman

Acoustic radiation due to vibration and impact of a spring-mass-damper oscillator whose motion is constrained by a barrier is analyzed at a field point in a free field. Impact betw…

Viscosity, shock-induced separation, and shock reversal -- Oscillating wing section in transonic flow

Pradeepa T. Karnick, Kartik Venkatraman

We numerically examine the mechanisms that describe the shock-boundary layer interactions in transonic flow past an oscillating wing section. At moderate and high angles of inciden…

Simultaneous excitation of phonons at the center and boundaries of Brillouin zones with high energy electron beams

Kartik Venkatraman, Peter A. Crozier

High energy electron beams can now be routinely focused to 1-2 Å and offer the ability to obtain vibrational information from materials using monochromated electron energy-loss spe…

Vibrational Spectroscopy at Atomic Resolution with Electron Impact Scattering

Kartik Venkatraman, Barnaby D. A. Levin, Katia March +2

Atomic vibrations control all thermally activated processes in materials including diffusion, heat transport, phase transformations, and surface chemistry. Recent developments in m…
