Special Issue Information

Dear Colleagues,

Internal combustion vehicles are being replaced by electric vehicles (xEVs) owing to the depletion of fossil fuels and higher emissions of greenhouse gases. xEVs are considered a promising technology for sustainable transportation in the future because of their zero-carbon footprint, high efficiency, and low noise. In the last few decades, fully electric vehicles, plug-in hybrid electric vehicles, fuel cell vehicles, and grid integrated electric vehicles have gained popularity due to advances reported in this technology. Despite significant research development, there exist some barriers that need to be addressed to ensure the full reliability of xEVs in the transport sector. The present Special Issue proposes a platform for presenting the latest research results, research solutions to the existing barriers, and technological advancements as they pertain to xEVs.

This Special Issue is focused on the recent research advances in xEVs, and includes, but is not limited to, the following topics:

  • Symmetrical/Asymmetrical design (including thermal, fluid flow, electrical, and structural aspects) for xEVs;
  • Thermal modeling and fluid flow analysis for xEVs;
  • Structural analysis for xEVs;
  • Thermal management of electric motors in xEVs;
  • Battery thermal management system for xEVs;
  • Efficient HVAC system for xEVs;
  • Power electronics (LEDs, inverters, converters, etc.) for xEVs;
  • Experimental, numerical, and analytical studies on xEVs;
  • Intelligent systems and algorithms for xEVs;
  • Optimization techniques for xEVs;
  • Energy management systems for xEVs;
  • Energy storage systems for xEVs;
  • Symmetry and asymmetry analysis for xEVs;
  • State-of-the-art reviews on xEVs.

The ferrofluid is a kind of nanofluid that has magnetization properties in addition to excellent thermophysical properties, which has resulted in an effective performance trend in cooling applications. In the present study, experiments are conducted to investigate the heat flow characteristics of ferrofluid based on thermomagnetic convection under the influence of different magnetic field patterns. The temperature and heat dissipation characteristics are compared for ferrofluid under the influence of no-magnet, I, L, and T magnetic field patterns. The results reveal that the heat gets accumulated within ferrofluid near the heating part in the case of no magnet, whereas the heat flows through ferrofluid under the influence of different magnetic field patterns without any external force. Owing to the thermomagnetic convection characteristic of ferrofluid, the heat dissipates from the heating block and reaches the cooling block by following the path of the I magnetic field pattern. However, in the case of the L and T magnetic field patterns, the thermomagnetic convection characteristic of ferrofluid drives the heat from the heating block to the endpoint location of the pattern instead of the cooling block. The asymmetrical heat dissipation in the case of the L magnetic field pattern and the symmetrical heat dissipation in the case of the T magnetic field pattern are observed following the magnetization path of ferrofluid in the respective cases. The results confirm that the direction of heat flow could be controlled based on the type of magnetic field pattern and its path by utilizing the thermomagnetic behavior of ferrofluid. The proposed lab-scale experimental set-up and results database could be utilized to design an automatic energy transport system for the cooling of power conversion devices in electric vehicles.
