Schlieren and PLIF imaging for hydrogen-air detonations
(Universidade Estadual Paulista (Unesp), 2019-12-13)
Application technologies based on the detonation cycle has proven a significant impact on the overall efficiency. However, detonation engines are not currently available on the markets due to the lack of physical and ...
Simultaneous Recording of Shadowgrams and Schlieren Images for the Study of Plasma Assisted Aerodynamics
(Japan Society Applied Electromagnetics & Mechanics, 2014)
Single camera time-resolved 3D tomographic reconstruction of a pulsed gas jet
(Springer, 2013-11)
Experimental characterization of micro-jets is challenging because of the small dimensions of the micro-nozzle. In this study, we propose a new technique to visualize the instantaneous 3D structure of a pulsed gas micro-jet. ...
Enhancement of synthetic schlieren image resolution using total variation optical flow: application to thermal experiments in a Hele-Shaw cell.
(2016)
We present an improvement to the standard synthetic schlieren technique to obtain the temperature distribution of a fluid inside of a Hele-Shaw cell. We aim to use the total variation L1-norm optical flow method to treat ...
A methodology for the digital reconstruction of an interferogram, a schlieren image, or a shadowgram from a single digital holographic recording
(2018)
This study presents an optical assembly and digital reconstruction method that is based on digital holography for characterizing transparent objects. The image-plane optical setup is based on a versatile Mach-Zehnder ...
Observation of preferred instability modes in a mechanically excited thermal plume using Schlieren visualizations
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-02)
An experimental study of the instability modes of a laminar axisymmetric thermal plume under symmetrical controlled disturbances of varicose type was carried out. The Schlieren technique was used to investigate the considered ...
