Summary

Two-phase flow is often utilized in energy systems to deal with thermal issues, such as generating steam in the boiler of the power plant and dissipating the heat in the condenser. In advanced energy systems, including Organic Rankine Cycle (ORC), Carnot battery, proton-exchange membrane fuel cell (PEMFC), CO2 capture process etc., two-phase flow still serves as a major role in the thermal energy transfer process. In addition, new issues arise in some applications, such as the coupled heat and mass transfer in the two-phase flow for PEMFC and the chemical reaction added in CO2 capture process. Consequently, understanding the fundamentals and mechanisms of heat and mass transfer of the two-phase flow is of great significance in order to develop advanced energy technology for engineering applications.

This special issue aims to report and disseminate the latest advances in two-phase flow in advanced energy systems.

 

Topics of interest include, but are not limited to:

• Two-phase flow and heat transfer in nano, micro, mini and macro-channels;

• Application of two-phase flow in ORC, PEMFC, Carnot battery, CO2 capture process and other advanced energy systems or processes;

• Boiling and condensation heat transfer;

• Fundamentals and mechanisms of two-phase flow and heat and mass transfer;

• Modeling and simulation of two-phase flow;

• Mass transfer coupled two-phase flow.

    Abstract In response to escalating challenges in energy conservation and emission reduction, this study delves into the complexities of heat transfer in two-phase flows and adjustments to combustion processes within coal-fired boilers. Utilizing a fusion of hybrid modeling and automation technologies, we develop soft measurement models for key combustion parameters, such as the net calorific value of coal, flue gas oxygen content, and fly ash carbon content, within the Distributed Control System (DCS). Validated with performance test data, these models exhibit controlled root mean square error (RMSE) and maximum absolute error (MAXE) values, both within the… More >

    Abstract With the advancement of oilfield extraction technology, since oil-water emulsions in waxy crude oil are prone to be deposited on the pipe wall, increasing the difficulty of crude oil extraction. In this paper, the mesoscopic dissipative particle dynamics method is used to study the mechanism of the crystallization and deposition adsorbed on the wall. The results show that in the absence of water molecules, the paraffin molecules near the substrate are deposited on the metallic surface with a horizontal morphology, while the paraffin molecules close to the fluid side are arranged in a vertical column More >

    Frontiers in Heat and Mass Transfer, Vol.22, No.1, pp. 193-216, 2024, DOI:10.32604/fhmt.2023.046832
    (This article belongs to the Special Issue: Two-phase flow heat and mass transfer in advanced energy systems)
    Abstract This study investigates the performance of a natural draft dry cooling tower group in crosswind conditions through numerical analysis. A comprehensive three-dimensional model is developed to analyze the steady-state and dynamic behavior of the towers. The impact of wind speed and direction on heat rejection capacity and flow patterns is examined. Results indicate that crosswinds negatively affect the overall heat transfer capacity, with higher crosswind speeds leading to decreased heat transfer. Notably, wind direction plays a significant role, particularly at 0°. Moreover, tower response time increases with higher crosswind speeds due to increased turbulence and More >
