Numerical Analysis of Blast Behavior for Non-ideal Explosive ANFO in Shock-Tube Test

open access: yesInternational Journal of Concrete Structures and Materials
In an explosion test using a shock tube, the behavior of pressure waves can be reproduced with high reliability. However, the explosion in a shock tube occurs in a confined space.

Examining shock wave flow past the brim of a helmet using schlieren imaging

open access: yesHeliyon
Increasing the protection a helmet provides the user from shock waves can help reduce the prevalence of blast induced traumatic brain injury (bTBI). Previous research has shown that air enters and gets trapped in the helmet-head cavity and can increase ...

Advances on Deflagration to Detonation Transition Methods in Pulse Detonation Engines

open access: yesEnergies
Pulse detonation engines (PDEs) have become a transformative technology in the field of aerospace propulsion due to the high thermal efficiency of detonation combustion. However, initiating detonation waves within a limited space and time is key to their

Meta-analysis of high-energy extracorporeal shock wave therapy in recalcitrant plantar fasciitis

open access: yesSwiss Medical Weekly, 2013
INTRODUCTION: Randomised controlled trials (RCTs) have reported conflicting results on whether extracorporeal shock wave therapy alleviates the pain of recalcitrant plantar fasciitis patients. We focused on high-energy extracorporeal shock wave therapy (HESWT) and aimed to assess the effectiveness and feasibility of HESWT versus placebo in the ...

Ignition Delay and Reaction Time Measurements of Hydrogen–Air Mixtures at High Temperatures

open access: yesFire
Induction and reaction times of hydrogen–air mixtures (ϕ = 0.5–2) have been measured behind reflected shock waves at temperatures of 1000–1600 K, pressures of 0.1, 0.3, 0.6 MPa in the domain of the extended second explosion limit.

Impact load bearing and energy absorption in sandwich polymer composites: Projectile versus shock loadings

open access: yesResults in Engineering
Two modalities of impact force application were utilized in this study: low velocity impact caused by a hemispherical projectile and shock wave. By utilizing a shock tube to generate the high-pressure shock waves, the sandwich composite panels were ...

Solar Particle Acceleration

open access: yesAstronomy
High-energy particles may be accelerated widely in stellar coronae; probably by the same processes we find in the Sun. Here, we have learned of two physical mechanisms that dominate the acceleration of solar energetic particles (SEPs).
