  journal={Shock Waves},
Experiments were performed to analyze the interaction of an explosively driven shock wave and a propane flame. A 30 g explosive charge was detonated at one end of a 3-m-long, 0.6-m-diameter shock tube to produce a shock wave which propagated into the atmosphere. A propane flame source was positioned at various locations outside of the shock tube to investigate the effect of different strength shock waves. High-speed retroreflective shadowgraph imaging visualized the shock wave motion and flame… 
An apparatus for producing tunable, repeatable, hydrogen–oxygen-deflagrative blast waves
The Hydrogen Unconfined Combustion Test Apparatus (HUCTA) was designed and built to study the blast waves produced from unconfined hydrogen/oxygen deflagrations. The HUCTA uses evacuated balloons of
Three-dimensional shock wave reconstruction using multiple high-speed digital cameras and background-oriented schlieren imaging
A methodology to perform three-dimensional reconstruction of an explosively driven shock wave’s position and shape as a function of time is developed here. A series of explosive tests are performed

We consider the linear stability to axisymmetric perturbations of the family of inviscid vortex rings discovered by Norbury (J. Fluid Mech., vol. 57, 1973, pp. 417–431). Since these vortex rings are
Particle image velocimetry (PIV) is an optical visualization and measurement technique that typically incorporates a single high-powered laser to illuminate seeded particles in a fluid flow. Standard
A review of recent developments in schlieren and shadowgraph techniques
Schlieren and shadowgraph techniques are used around the world for imaging and measuring phenomena in transparent media. These optical methods originated long ago in parallel with telescopes and


Shock Wave Interaction with a Flame
Shock wave/fire interactions initiated by high explosives have been historically demonstrated as potentially effective ways to control oil well fires or even forest fires in situations where
Interactions of shock tube exhaust flows with laminar and turbulent flames
The interactions of flow features emitting from open-ended shock tubes with free-standing propane flames have been investigated using high-speed schlieren imaging and high-frequency pressure
Discharge of a shock Wave from an Open End of a Tube
When a pressure wave propagates along a constant area straight tube and reaches at the open end,an impulsive wave is emitted outwared from the tube exit toward the surrounding area and causes an
Numerical simulation and PIV study of compressible vortex ring evolution
Formation and evolution of a compressible vortex ring generated at the open end of a short driver section shock tube has been simulated numerically for pressure ratios (PR) of 3 and 7 in the present
Characteristics of counter-rotating vortex rings formed ahead of a compressible vortex ring
Characteristics of high Mach number compressible vortex ring generated at the open end of a short driver section shock tube is studied experimentally using high-speed laser sheet-based flow

Experiments by Phan & Stollery (In Proc. 14th International Symposium on Shock Tubes and Waves, pp. 519-526 (1983)) indicated the presence of a supersonic vortex ring with an embedded rearward-facing
Optical measurement and scaling of blasts from gram-range explosive charges
Laboratory-scale experiments with gram-range explosive charges are presented. Optical shadowgraphy and high-speed digital imaging are used to measure the explosive-driven shock-wave position as a
Fluid entrainment by isolated vortex rings
Of particular importance to the development of models for isolated vortex ring dynamics in a real fluid is knowledge of ambient fluid entrainment by the ring. This time-dependent process dictates
