Vibrational effects on the dynamic pressure measurement standard based on a diaphragmless shock tube

open access: yesMeasurement: Sensors, 2021
This paper determines the vibrational effects on a diaphragmless shock tube, which was developed for dynamic calibrations of pressure transducers. First, the sensitivity to acceleration of the piezoelectric pressure transducer was determined by exciting the end-wall shock tube flange with the pressure transducer mounted.

Design of Diaphragmless Shock Tube and Research on its Normal Temperature Characteristics

open access: yesJournal of Physics: Conference Series, 2020
Abstract Shock wave is an important physical phenomenon in supersonic airflow. The shock tube is an experimental device that generates shock wave. It generates shock wave by generating a pressure difference between its high-pressure section and low-pressure section.

Initiation and Carbene Induced Radical Chain Reactions in CH2F2 Pyrolysis

open access: yesChemPhysChem, Volume 25, Issue 15, August 1, 2024.
A multi‐diagnostic experimental effort supported by ab‐initio based theoretical kinetics predictions and kinetics modeling resolves uncertainties in the initiation kinetics and identifies new secondary pathways in CH2F2 thermal dissociation. Abstract High temperature dissociations of organic molecules typically involve a competition between radical and

Liquid Film Condensation behind Shock Waves on the Cold Wall of a Diaphragmless Vertical Shock Tube: An Experimental Study

open access: yesJournal of Applied Fluid Mechanics, 2022
The aim of this study was to investigate the condensation of HFC-134a vapor on a shock tube wall behind shock waves. The time-dependent thickness of the condensed liquid film was measured using an optical interference method based on multiple reflections of a laser beam.

Implementation of novel methods for new insights into the autoignition behavior of hydrogen–air mixtures at lean and ultra-lean conditions [PDF]

open access: yes
Lean burn is increasingly recognized as a prospective operational mode for diverse combustion systems, with the potential to reduce combustion temperatures and thereby lower NOx emissions. However, challenges arise due to the lower flammability limit and
