Hydrogen, known for its high flammability and potential explosive characteristics, presents significant challenges in safety engineering, particularly in enclosed spaces where explosions can lead to catastrophic consequences. This paper presents the results of physical experiments conducted to investigate the linear propagation of hydrogen explosions within confined environments. The experiments were designed to simulate real-world scenarios and assess the factors influencing the extent and characteristics of expl...

The effect of pressurized hydrogen on pipeline walls is an important phenomenon that can cause damage to the integrity of the pipeline structure during transport and storage of gases. Hydrogen can penetrate the wall of metallic pipelines (alloy steel or carbon steel) and cause cracking or rupture of the material, which can lead to pressure loss or even serious effects (explosions, fires). The embrittlement of the metal by hydrogen is a phenomenon of degradation of the mechanical properties of the metal, as a resul...

According to ANSYS - developer of the Multiphysics platform for computer simulations - the FSI (Fluid-Structure Interaction) model can be used in all cases where a fluid encounters a solid structure, for example, wind gusts rotating a turbine, air washing the surface of a moving car etc. This method finds applications especially in the aeronautical and automotive industries, but also in medical research, such computer simulations track the influences of blood pressure and blood flow velocity in the veins. This pap...

The identification technique of hazardous clouds using infrared spectrometry is based on the spectral analysis of electromagnetic radiation that is absorbed and emitted by the molecules of a gas cloud. Molecules can be identified by analyzing the location of lines inside the spectrum, representing the energy differences between the cases involved and the strength of the lines, which is the probability of a photon being absorbed or emitted. This method is often called passive infrared spectrometry because no artifi...
