Ballistic impact protection is essential in defense, aerospace, and personal safety applications, where materials must absorb and mitigate high-velocity impacts to ensure performance and safety. Traditionally, gas gun ...

The burgeoning demand for efficient and sustainable Aerial Vehicles (AVs) requires the development of powertrain systems tailored to specific mission requirements. Current AVs are incorporating hybrid-electric powertrains, ...

The Deep Underground Neutrino Experiment (DUNE) is an international collaboration investigating neutrino physics. One of the key objectives is to understand the start of the universe. What causes asymmetry to occur between ...

A solid cryocooler is defined as any device by which standard cryogenic working fluids are eschewed in whole or in part and are replaced with working solids. Despite its overall greater potential for reaching lower ...

In partnership with the US Department of Energy, SolarDynamics, and Atlantica, the solar-simulator project was undertaken developing training software for control room operators of parabolic trough concentrating solar power ...

Topology optimization (TO) is a powerful and widely used design methodology in structural engineering and product design. While numerous academic software tools exist for 2D and 3D TO, they often focus on relatively simple ...

Phase change material (PCM) thermal energy storage (TES) heat exchangers (HXs) have the potential to shave and shift loads behind the meter if integrated into heat pumps as a substitute for the outdoor coil during discharge. ...

This study investigates the impact of sensor location on accelerometer-based sensing of combustion phasing for compression-ignition engines. Ten accelerometer locations were studied on a light-duty compression-ignition ...

In a pulse tube cryocooler, the pulse tube acts as an adiabatic “gas piston”, whose function is to transport work from a cryogenic region to a warmer region, where it can be rejected as heat. Mass streaming effects, which ...

This study evaluates the technical and economic impact of a topology-optimized silicon carbide (SiC) primary heat exchanger on the energy-specific cost and optimized design of Gen3 concentrated solar power (CSP) plants. ...
