Numerical simulation of drop weight impact sensitivity evaluation criteria for pressed PBXs
Defence Technology, 2023 A thorough understanding of drop-weight impacted responses for polymer-bonded explosives (PBXs) is significant to evaluate their impact sensitivity. The characteristics of the drop-weight impacted pressed PBXs including deforming, fracturing, forming a ...

The Minimum Ignition Energy of Powder Mixtures
Chemical Engineering Transactions, 2016 The minimum ignition energy (MIE) is one of the most important parameters for the assessment of explosion risks and the design of protection concepts when handling combustible powders. With the introduction of the ATEX regulation in Europe, the issue of ignition source analysis has become relevant not only in large bulk production plants where mostly ...

METHOD OF CALCULATION OF AIR-FUEL MIXTURE MINIMUM IGNITION ENERGY IN GAS ENGINE [PDF]
Avtomobilʹnyj Transport (Harʹkov), 2013 The improved method of minimum ignition energy calculation in a gas engine that takes into account radiation energy losses in a flame kernel has been presented. Comparison of calculation results using this model with experimental data has been performed.

Laser ignition of iso-octane air aerosols [PDF]
, 2008 Iso-octane aerosols in air have been ignited with a focused Nd:YAG laser at pressures and temperatures of 100kPa and 270K and imaged using schlieren photography. The aerosol was generated using the Wilson cloud chamber technique.

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
