Influence of geometry on the compressive behaviour and energy absorption of 3D-Printed honeycomb, auxetic, and hybrid sandwich cores

The mechanical performance of additively manufactured sandwich cores is governed by cellular topology and process-induced anisotropy. This study investigates the quasi-static compressive behaviour and failure-based energy absorption of fused deposition modelling (FDM) printed pol...

Convex Optimization Strategies for Energy‐Efficient Beamforming in Satellite Communications

ABSTRACT A trend in the design and development of beamforming has emerged as a critical issue in modern satellite communications, particularly with the emergence of low Earth orbit (LEO) satellite constellations. This paper presents a comprehensive system for energy‐efficient bea...

Study on the solid-liquid two-phase flow characteristics of coolant pumps for energy storage system at different rotational speeds

Coolant pumps are critical for liquid cooling in energy storage systems, regulating coolant circulation through speed adjustments to maintain optimal temperatures. However, particles in the system cause pump erosion, threatening equipment lifespan and system safety. The multiphas...
