Summary
The ongoing pursuit of higher efficiency, power density, and reliability in power and energy systems has placed heat and mass transfer at the centre of technological innovation. This Special Issue aims to gather high-quality contributions addressing the fundamental and applied challenges of heat and mass transfer across a broad spectrum of power-related applications. Original research articles and comprehensive reviews are equally welcome.
The scope of this Special Issue is intentionally broad and interdisciplinary. Topics of interest include, but are not limited to, the following areas:
· Multiphase flow and phase-change heat and mass transfer
· Combustion-driven heat and mass transfer, spray dynamics, and mixture formation
· Conjugate heat transfer and thermal management for high-power-density components
· Multi-scale and multi-physics modelling, numerical simulation, and novel measurement techniques
· Heat and mass transfer in energy conversion, storage, and thermal control systems
Reflecting the combined expertise of the Guest Editors, particular attention will be given to advances in multiphase flow heat and mass transfer and combustion-related heat and mass transfer. At the same time, contributions on all related themes that advance the understanding or application of heat and mass transfer in power systems are strongly encouraged. Topics falling outside the above list but fitting the general scope are equally welcome.
