Surface Condensation in the Presence of Non-Condensable Gases: Part II. Experimental Investigations and Controlling Factors

Simulation of Condensation Flow and Heat Transfer in Spiral Tube Heat Exchangers for Non-Azeotropic Hydrocarbon Mixtures.

As a core component of the natural gas liquefaction process, spiral wound heat exchangers play a crucial role in LNG production. To comprehensively understand the condensation flow and heat transfer characteristics of non-azeotropic hydrocarbon mixtures inside spiral tubes. The high-precision numerical investigation in...

Numerical modeling of a metallic alloy droplet impact, solidification, and macrosegregation

For the first time, we study the effects of mass transfer on alloy droplet impact, solidification, and solute non-homogeneity or MacroSegregation (MS). For this purpose, a multi-physics model, including fully-coupled hydrodynamics of multiphase flow, wetting, conjugate heat transfer, phase change, and mass transfer, is...

Unifying Physics, Structure, and Function in Solar Interfacial Evaporation: A Multiscale Perspective.

Solar interfacial evaporation (SIE) has emerged as a low-carbon, sustainable route for seawater desalination and water purification, yet its development remains constrained by intrinsic heat loss, vapor-diffusion resistance, and insufficient interfacial energy management. Furthermore, advances in materials and architec...

Interfacial instabilities and thermo-hydrodynamic mechanisms in high-temperature vapour-ventilated supercavitation

Abstract Content of image described in text. This study experimentally investigates the interfacial instabilities and thermo-hydrodynamic mechanisms of supercavities ventilated by high-temperature condensable vapour. Using high-speed imaging with an AI-based segmentation model, we establish a flow regime map that delin...

Phase-Change Transpiration Cooling for Hypersonic Vehicles: A Comprehensive Review of Mechanisms, Modeling, Experiments, and Future Direction

Phase-change transpiration cooling, in which a liquid coolant flows through a porous medium, absorbs heat, and undergoes phase change while forming a protective gas film, is widely regarded as one of the most efficient active thermal protection concepts for next-generation hypersonic vehicles. This paper presents a com...
