A summary of recent research progress in hypersonic plasma actuators for flow control is
attempted. It is found that the most effective plasma actuator is derived from an …

Typical challenges of supersonic flight include wave drag, acoustic signature, and
aerodynamic heating due to the formation of shock waves ahead of the vehicle. Efforts in the …

Experiments were conducted to quantify the temperature and electron number density of a
laser spark formed in air. The laser spark was created by focusing a 180-mJ beam from the …

A detailed investigation of the effect of ambient pressure in the range of 0.1 to 1.0 atm on the
size, temperature, electron number density, and fraction of laser energy absorbed in a laser …

SHOCK wave/boundary-layer interactions (SWBLIs) are a common feature of
supersonic/hypersonic flight, and the unsteadiness of strongly separated interactions can …

ONE of the major challenges of hypersonic flight is aerodynamic control. Current hypersonic
test vehicles (eg, X-34 [1], X-43A [2]) fly with movable aerodynamic surfaces. For DARPA's …

THE USE of plasma actuators for active flow control is a widely investigated topic in fluid
mechanics research. The promise of having no mechanical components, no fuel or mass to …

Temperature and pressure profiles are computed by the use of a two-dimensional, axially
symmetric, time-accurate computational fluid-dynamic model for nominal 10-ns optical …

We present applications of laser-energy deposition for drag reduction in supersonic flow.
The system of chemically reactive Navier–Stokes equations describes the hydrodynamics …

Numerical simulations of laser energy deposition in air are conducted. Local thermodynamic
equilibrium conditions are assumed to apply. Variation of the thermodynamic and transport …
