Flow Field Simulation and Efficiency Calculation of Muzzle Brake Based on ANSYS Fluent [PDF]

E3S Web of Conferences, 2021
The development of advanced artillery needs to be combined with simulation means, so, traditional calculation method and the flow field simulation method was employed to calculate the efficiency of a largecaliber muzzle brake we designed, and the results

Penetration and internal blast behavior of reactive liner enhanced shaped charge against concrete space

Defence Technology, 2022
Penetration and internal blast behavior of reactive liner enhanced shaped charge against concrete space were investigated through experiments and simulations. The volume of the enclosed concrete space is about 15 m3.

Numerical investigation on free air blast loads generated from center-initiated cylindrical charges with varied aspect ratio in arbitrary orientation

Defence Technology, 2022
In current guidelines, the free air blast loads (overpressure and impulse) are determined by spherical charges, although most of ordnance devices are more nearly cylindrical than spherical in geometry.

Effects of intravitreal injection of siRNA against caspase-2 on retinal and optic nerve degeneration in air blast induced ocular trauma

Scientific Reports, 2021
Ocular repeated air blast injuries occur from low overpressure blast wave exposure, which are often repeated and in quick succession. We have shown that caspase-2 caused the death of retinal ganglion cells (RGC) after blunt ocular trauma.

Non-linear long-duration blast loading of cylindrical shell structures [PDF]

, 2014
This paper investigates the influence of long-duration blast loads on the structural response of aluminium cylindrical shell structures. Full scale coupled non-linear dynamics are examined experimentally at one of the worlds’ most powerful air blast ...

Simulation of the generation and propagation of blast induced shock waves [PDF]

, 2003
Hybrid modelling of blast vibration uses the signal produced from a single hole test shot to simulate the vibration that would be produced by a full-scale production blast.

Forecasting research of overpressure of explosive blast in subway tunnels [PDF]

, 2015
In case of an explosion happening inside the subway tunnel, blast waves interacts with the structure in an enclosed space. Both the overpressure and duration of blast increase.

Localizing Clinical Patterns of Blast Traumatic Brain Injury Through Computational Modeling and Simulation

Frontiers in Neurology, 2021
Blast traumatic brain injury is ubiquitous in modern military conflict with significant morbidity and mortality. Yet the mechanism by which blast overpressure waves cause specific intracranial injury in humans remains unclear.

Blast wave mitigation performance of rapid-assembly anti-blast walls under explosion of large magnitude

Results in Engineering
This study evaluated the blast wave mitigation performance of single-layer and double-layer rapid-assembly Anti-Blast Walls. A single near-ground blast experiment was conducted using 602 kg of TNT.

Internal Carbon Cycles in the Steel Industry: Pathways for CO2 Management and Carbon Capture Utilization

Chemie Ingenieur Technik, EarlyView.
The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.
