Summary

The urgent demand for efficient heat dissipation methods in the fields of electric vehicles and hybrid electric vehicles, aerospace vehicles, electronic equipment, solar energy collectors and nuclear reactors, encourages blooming studies on active cooling. Designing novel structures and preparing new coolants are effective ways to enhance cooling efficiency, which plays an essential role in the prospective developments of these engineering fields. The characteristics of fluid flow, heat and mass transfer within the novel cooling structure have scientific and technological significance and thereby are the current research focuses of active cooling. This Special Issue is dedicated to the novel results in theoretical, experimental, and numerical studies of novel active cooling structures with single-phase and multi-phase flows. The current advancements in the research methods for exploring the thermal and flow physics relevant to active cooling structures are also of interest.

 

Topics of interest include, but are not limited to:

• Single- and two-phase flows within porous structure and microchannel;

• Active cooling using new fluid medium;

• Cooling enhancements of gas turbine;

• Performance improvements of the heat pipe;

• Thermal management in fuel cell;

• Heat transfer enhancement in circulating pipe flow;

• Heat exchanger;

• Electronic cooling;

• Novel methods in experiments, modeling and simulation of fluid flow, heat and mass transfer within novel cooling structures.

    Cooling and Optimization in the Groove of the Outer Rotor Hub Motor

    Zhuo Liu, Yecui Yan
    Frontiers in Heat and Mass Transfer, DOI:10.32604/fhmt.2024.056091
    (This article belongs to the Special Issue: Fluid Flow, Heat and Mass Transfer within Novel Cooling Structures)
    Abstract The external rotor hub motor adopts direct drive mode, no deceleration drive device, and has a compact structure. Its axial size is smaller than that of a deceleration-driven hub motor, which greatly reduces the weight of the vehicle and increases the cruising range of the vehicle. Because of the limited special working environment and performance requirements, the hub motor has a small internal space and a large heat generation, so it puts forward higher requirements for heat dissipation capacity. For the external rotor hub motor, a new type of in-tank water-cooled structure of hub motor… More >

    Impact of Viscous Dissipation and Ohmic Heating on Natural Convection Heat Transfer in Thermo-Magneto Generated Plume

    Sahar Anwar, Ghulam Rasool, Muhammad Ashraf, Uzma Ahmad, Tao Sun
    Frontiers in Heat and Mass Transfer, DOI:10.32604/fhmt.2024.055314
    (This article belongs to the Special Issue: Fluid Flow, Heat and Mass Transfer within Novel Cooling Structures)
    Abstract The present investigation centers on the impact of viscous dissipation and ohmic heating on the plume generated by a line heat source under the impact of an aligned magnetic field. In this study, the flow model is adapted to incorporate ohmic heating and viscous dissipation by including the respective terms in the energy equation. A mathematical model is formulated as a system of coupled partial differential equations to analyze the flow problem. Subsequently, a numerical solution is derived with stream function formulation for the system of coupled partial differential equations, which transmutes it into ordinary… More >

    Enhanced Evaporation of Ternary Mixtures in Porous Medium with Microcolumn Configuration

    Bo Zhang, Yunxie Huang, Peilin Cui, Zhiguo Wang, Duo Ding, Zhenhai Pan, Zhenyu Liu
    Frontiers in Heat and Mass Transfer, Vol.22, No.4, pp. 997-1016, 2024, DOI:10.32604/fhmt.2024.053592
    (This article belongs to the Special Issue: Fluid Flow, Heat and Mass Transfer within Novel Cooling Structures)
    Abstract The high surface area of porous media enhances its efficacy for evaporative cooling, however, the evaporation of pure substances often encounters issues including local overheating and unstable heat transfer. To address these challenges, a volume of fluid (VOF) model integrated with a species transport model was developed to predict the evaporation processes of ternary mixtures (water, glycerol, and 1,2-propylene glycol) in porous ceramics in this study. It reveals that the synergistic effects of thermal conduction and convective heat transfer significantly influence the mixtures evaporation, causing the fluctuations in evaporation rates. The obtained result shows a More >
