TL;DR: In this article, a high-speed imaging setup was utilized to visualize the shock tube cross-section through a transparent quartz end-wall, and the results suggest that premature ignition events are more likely to happen in mixtures containing higher ethanol concentration and that preignition energy release is more pronounced at lower temperatures.

TL;DR: In this paper, the authors report the design and implementation of a novel imaging section which enables simultaneous lateral and endwall imaging by using a longitudinal slit window, which maintains the circular structure of the shock wave and allows lateral imaging as far as 300mm from the shock tube endwall.

TL;DR: In this article, experimental and computational investigations are carried out to identify the generalized criterion to predict the preignition tendency of methanol and ethanol mixtures in shock tubes, and the Sankaran number criterion (Sap) was found to be the most successful predictor of the experimental observations.

TL;DR: In this paper, a dual-camera setup has been used with an optical end-section in a circular shock tube to obtain simultaneous high-speed images from the shock tube endwall and sidewall, thus providing visualization of the ignition phenomenon in three dimensions.

TL;DR: In this article, the mechanical properties of cement-chitin mixtures are investigated with different percentages of chitin (0.5, 1.3, and 2.1 wt%) and aging of composite in a joint nanoscopic- and macroscopic-scale by experimental study.
