Schlieren and shadowgraph techniques are used around the world for imaging and
measuring phenomena in transparent media. These optical methods originated long ago in …

We compare the results of three quantitative schlieren techniques applied to the
measurement and visualization of a two-dimensional laminar free-convection boundary …

Understanding the mechanism of positive leader discharge is important in lightning
protection engineering and the external insulation design in high voltage power …

This paper investigates the application of a 3D density reconstruction from a limited number
of background-oriented schlieren (BOS) images as recently proposed in Nicolas et al.(Exp …

ABSTRACT A number of distinctions between conventional schlieren and rainbow schlieren
give rise to the qualitative versus quantitative nature of each technique. The present paper …

The Mach–Zehnder interferometer with the finite fringe method is applied for the first time to
diagnose the three-dimensional density field of a shock-containing microjet issued from a …

The rainbow schlieren deflectometry has been combined with the computed tomography to
obtain three-dimensional density fields of shock containing free jets and we call the method …

Instantaneous three-dimensional (3D) density distributions of a shock-cell structure of
perfectly and imperfectly expanded supersonic microjets escaping into an ambient space …

The work reports on simultaneous measurement of bubble dynamics and thermal field to
understand the local effects of bubble motion on thermal boundary layer behavior and heat …

In this study, air-jet experiments were performed to investigate the effects of nozzle pressure
ratios (n) on the pulsation frequency and structure of free-flow and impinging-flow fields. The …
