Active Flow Control of NACA 0012 airfoil using Sawtooth Direct Current Augmented Dielectric Barrier Discharge Plasma Actuator
Ravi Sankar Vaddi, Charles Sota, Alexander Mamishev +1
Dielectric barrier discharge (DBD) plasma actuators are an attractive option for separation control, lift enhancement, and drag reduction. Some plasma actuators feature optimized e…
Empirical Model for Discharge Current and Momentum Injection in Dielectric Barrier Discharge
Anthony Tang, Ravi Sankar Vaddi, Alexander Mamishev +1
Dielectric Barrier Discharge (DBD) plasma actuators with an asymmetric, straight edge electrode configuration generate a wall-bounded jet without moving parts. Mechanistic descript…
Analytical Model for Electrohydrodynamic Thrust
Ravi Sankar Vaddi, Yifei Guan, Alexander Mamishev +1
Electrohydrodynamic (EHD) thrust is produced when ionized fluid is accelerated in an electric field due to the momentum transfer between the charged species and neutral molecules.…
Comparison of Analytical and Numerical Models for Point to Ring Electro-Hydrodynamic Flow
Yifei Guan, Ravi Sankar Vaddi, Alberto Aliseda +1
An electrohydrodynamic (EHD) flow in a point-to-ring corona configuration is investigated experimentally, analytically and via a multiphysics numerical model. The interaction betwe…
Experimental and Numerical Investigation of Corona Discharge Induced Flow on a Flat Plate
Ravi Sankar Vaddi, Yifei Guan, Zhi Yan Chen +2
Electrohydrodynamic (EHD) flow induced by planar corona discharge in the wall boundary layer region is investigated experimentally and via a multiphysics computational model. The E…
A laser-microfabricated electrohydrodynamic thruster for centimeter-scale aerial robots
Hari Krishna Hari Prasad, Ravi Sankar Vaddi, Yogesh M Chukewad +3
To date, insect scale robots capable of controlled flight have used flapping wings for generating lift, but this requires a complex and failure-prone mechanism. A simpler alternati…
