As is well known, hydrogen exhibits a wide flammability range, low ignition energy, and high diffusivity, which create significant explosion risks in storage and handling facilities. Therefore, the development of effective methods and devices for the detection and control of hydrogen explosions is essential to ensure operational safety. This paper presents the development and experimental validation of an explosion control device intended for hydrogen storage systems. The proposed device is based on an optical ult...

In this study, we present the design and implementation of an experimental stand tailored for the analysis of hydrogen explosions with the capability of modifying the propagation direction. Hydrogen explosions pose significant safety concerns in various industrial settings, and understanding their behavior under different conditions is crucial for risk assessment and mitigation strategies. The experimental setup integrates precise control mechanisms to manipulate the direction of explosion propagation, allowing fo...

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 use of natural gas as a home heating source has, unfortunately, generated a number of gas explosion events, most of which have as their main cause the accidental leakage of combustible gas. The dynamic effects generated by the explosion pressures differ from case to case, depending on the concentrations of combustible gas accumulated in the chambers from the time of the occurrence of the gas leak to the occurrence of the source of initiation. Often, these dynamic effects involve concentrations close to the sto...
