Turbulent pair dispersion in the presence of gravity

New Journal of Physics, 2015
Turbulent pair dispersion of heavy particles is strongly altered when particles of two different Stokes numbers (bidisperse) are considered, and this is further compounded when a uniform gravitational acceleration is present.

Reverse design of solid propellant grain based on deep learning: Imaging internal ballistic data

Defence Technology
The reverse design of solid rocket motor (SRM) propellant grain involves determining the grain geometry to closely match a predefined internal ballistic curve. While existing reverse design methods are feasible, they often face challenges such as lengthy

Research on ballistic performance of green shear thickening functionalized fabric based on solid waste modification

Materials & Design
Based on the solid waste-based modification, green shear-thickening functionalized ballistic composites were prepared. Silica aerosols were obtained from solid waste diatomaceous earth through sol–gel preparation, gel aging, and supercritical drying. The

Long-term natural ageing effects on the structural, mechanical, and ballistic performance of UHMWPE-based soft ballistic inserts

Materials & Design
The aim of the study was to evaluate the degradation mechanisms of ultra-high molecular polyethylene (UHMWPE) fibres used in soft ballistic inserts manufactured in 2003 and 2005 and used and stored in conditions typical for this type of products.

Failure after operative repair is higher for ballistic femoral neck fractures than for closed, blunt-injury fractures: a multicenter retrospective cohort study

Trauma Surgery & Acute Care Open
Introduction The purpose of this study was to describe the outcomes after operative repair of ballistic femoral neck fractures. To better highlight the devastating nature of these injuries, we compared a cohort of ballistic femoral neck fractures to a ...
