Simulation study of influence of the outlet elastic baffle on pressure in arc chamber during the interrupting process of low-voltage circuit breaker

AIP Advances, 2021
In this paper, a bidirectional fluid–solid interaction method is established to investigate the influence of the outlet elastic baffle on the pressure in the arc chamber in the breaking process of a low-voltage circuit breaker. Based on the computational

High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

Advanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Numerical Study of Ejector–Diffuser Coupling and Hysteresis in an Active-Ejection High-Altitude Simulation Test Stand

Aerospace
Engine high-altitude simulation tests require establishing a stable low test-chamber pressure across a wide range of operating conditions. Existing studies focus predominantly on the local starting mechanisms—namely, shock-wave swallowing, aerodynamic ...

Microstructure‑Dependent Phase Transformations Under High‑Pressure Laser Heating in Additively Manufactured AlCrFe2Ni2

Advanced Engineering Materials, EarlyView.
Additively manufactured AlCrFe2Ni2 with contrasting BCC/B2‐dominant and lamellar FCC + BCC/B2 microstructures exhibits the same pressure‐induced BCC/B2 → HCP transformation. Under laser heating at high pressure, HCP is destabilized, and a cubic BCC/B2 + FCC assemblage is recovered, while the lower‐scan‐speed microstructure transforms at a lower ...

AMRL Dynamic Pressure Chamber [PDF]

The Journal of the Acoustical Society of America, 1973
The AMRL dynamic pressure chamber is an infrasonic simulator expressly designed for biomedical research. This device simulates the low-frequency (0.5–30 Hz) noise spectrum associated with jet aircraft and rocket launches. Being an electrohydraulic device, it can simulate periodic, random, or impulsive types of environment.

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel

Advanced Engineering Materials, EarlyView.
Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...
