Article Abstract
The electric field is known as an effective approach to improving pool boiling. However, there has been limited research on electric field-enhanced boiling of leaky dielectric fluids and the associated bubble dynamics. In this work, we employ a mesoscopic multiphase lattice Boltzmann method to perform large-scale three-dimensional simulations of electric field-enhanced pool boiling in leaky dielectric fluids. Our findings confirm that, compared to conventional pool boiling, electric field-enhanced pool boiling significantly increases heat transfer efficiency in the transition boiling regime. Furthermore, we propose a theoretical model based on the hydrodynamic theory that accurately predicts the heat flux across a wide range of operating parameters. Finally, we reveal size effects of the electric force on nucleation sites and rising bubbles, explaining the contrasting phenomena of bubble suppression and enhanced bubble detachment observed in electric field-enhanced boiling. The results of this study provide theoretical insight for optimizing phase‑change heat transfer efficiency.

To achieve robust and high-efficient thermal management at micro scale, this study focuses on interplay of a micro bubble blanket and lifting large bubbles on locally heated surfaces with nano-ridge structures. The micro bubble blanket covers the surface dynamically after heat fluxes exceed a criterion where heat transfer coefficients exhibit constant values, highlighting the robust and predictable two-phase heat transfer. By quantitative investigations of diameters as well as lifting speed of large bubbles, it ensures that convective boiling heat transfer mechanism dominates without forced convection, accounting for constant heat transfer coefficient at high-heat-flux regions.

This study demonstrates an efficient boiling heat transfer (BHT) interface achieved through patterned islands covered with nanocones. Through systematic investigation of copper microcavity and nanocone (CMN) composite structure morphology evolution, an optimized structure was identified by various characterizations including wettability characteristics, boiling mass and heat transfer performance. Structural modification yielded hybrid patterned island structures with a significantly enhanced performance.

Accurate monitoring of boiling heat transfer is critical for the safety and efficiency of high energy-density systems, including data center cooling, nuclear reactors, and industrial boilers. Traditional diagnostic methods relying on intrusive sensors or visual inspection become impractical in harsh industrial environments characterized by high pressures, temperatures, and radiation exposure. In this paper, we propose a non-intrusive diagnostic framework combining externally measured acoustic emission (AE) signals with advanced deep learning techniques.

Plasmonic heating of gold nanoparticles (GNPs) using pulsed lasers (PLs) enables microbubble generation for imaging, diagnostics, and microfluidics. However, aggregation and photomodification cause inconsistencies (variations) in microbubble formation and distribution, particularly in pool-like environments where GNPs undergo aggregation and photomodification. This study experimentally investigates microbubble generation by heating GNPs (532 nm, nanoseconds PL) of various sizes and concentrations, using high-speed imaging (20 kfps).

Pool boiling offers exceptional heat transfer performance, making it crucial for advanced thermal management. However, simultaneously optimizing both critical heat flux (CHF) and heat transfer coefficient (HTC) is challenging due to the inherent trade-off between promoting bubble nucleation and mitigating detrimental bubble coalescence. This study presents a micro/nano-hierarchical surface architecture designed to overcome this limitation.
