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

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 …

Understanding of the structure of complex supersonic flows requires high-resolution,
nonintrusive measurements across the whole field. The measurement requirements are …

The rainbow schlieren deflectometry (RSD) technique is used to determine the liquid
boundary and the fuel volume fraction distributions in the vapor region of a high-pressure …

Imaging fluid flow and transport phenomena has gained considerable attention in the recent
past. The imaging techniques are not only limited to visualization tools but, when coupled …

Detailed experimental comparisons had been conducted between calibrated and rainbow
schlieren on perfectly-and under-expanded axisymmetric supersonic jets through a modified …

Shock-free ion transmission from atmospheric pressure to a microelectromechanical system
(MEMS)-based mass spectrometer has been achieved using micro-engineered nickel …

An experimental setup applying Rainbow Schlieren Deflectometry (RSD) is developed and
used successfully for non-invasive measurement of thermal free convection. Tempered …

A quantitative rainbow schlieren study was conducted on an over-expanded jet at nozzle
pressure ratio of 2.8, based on two different schlieren set-ups: the standard z-type and a …
