Autor: Yojiro Ishino, Yuta Ishiko, Harumi Kondo, Ryoya Yamada, Takanori Motohiro, Shinichiro Nakao, Ahmad Zaid Nazari, Fumiya Ito, Yoshiaki Miyazato
Publikováno v: Journal of Flow Control, Measurement & Visualization. :77-101
Instantaneous three-dimensional (3D) density distributions of a shock-cell structure of perfectly and imperfectly expanded supersonic microjets escaping into an ambient space are measured. For the 3D observation of supersonic microjets, non-scanning

Autor: Yojiro Ishino, Ahmad Zaid Nazari, Yu Saiki, Fumiya Ito, Ryoya Yamada, Shinichiro Nakao, Yoshiaki Miyazato, Takanori Motohiro, Harumi Kondo
Publikováno v: Journal of Flow Control, Measurement & Visualization. :25-44
This report deals with introducing two new techniques based on a novel concept of complex brightness gradient in quantitative schlieren images, “inverse process” and “multi-path integration” for image-noise reduction. Noise in schlieren image
