On the use of quantitative Schlieren techniques in temperature measurement of leader discharge channels

Plasma Sources Science & Technology, 2019
Electrical discharges in long air gaps, referred to as ‘leader discharges’, usually propagate with transient thermal plasma channels. The gas temperature evolution of the channels plays a key role in the inception and development of leader discharges ...

The Schlieren Technique

2001
The measuring-principle of the schlieren technique is based on the deflection of a collimated light beam crossing gradients of the index of reflection in a transparent medium. It is, therefore, suited for applications in which deviations of light are intended to be visualized as they appear e.g.

Rainbow schlieren-based direct visualization of thermal gradients around single vapor bubble during nucleate boiling phenomena of water

International Journal of Multiphase Flow, 2019
Real time non-intrusive diagnostics of thermal gradients around a single vapor bubble in isolated nucleate pool boiling with water as the working fluid have been presented.

Schlieren-based simultaneous mapping of bubble dynamics and temperature gradients in nucleate flow boiling regime: Effect of flow rates and degree of subcooling

Experimental Thermal and Fluid Science, 2019
Bubble dynamics and the local thermal field associated with single nucleating bubble under subcooled flow boiling conditions have been investigated in a one side-heated rectangular channel with water as the working fluid.

Dynamic photorefractive Schlieren system

Applied Optics, 1993
We present a dynamic Schlieren system that uses optical phase conjugation in a photorefractive crystal. The theoretical description of the system predicts that the square of the phase change in an object field is mapped as the intensity modulation in the system output.

Studies on the effect of imaging parameters on dynamic mode decomposition of time-resolved schlieren flow images

Aerospace Science and Technology, 2019
Dynamic modal analysis enables new insights into the spatio-temporal dynamics of complex flow scenarios. Time resolved schlieren imaging provides significant information in compressible flow scenarios on flow structures and their evolution.

Criteria for Quantitative Schlieren Interferometry

Applied Optics, 1967
An evaluation is made of a criterion suggested by Temple for the size and location of obstacles in the focal plane of a schlieren interferometer. Measurements of the thermal distributions near a heated vertical plate and near a heated horizontal cylinder are presented.
