TL;DR: In this article, an experimental investigation was conducted to explore the validity of classical correlations based on conventionalsized channels for predicting the thermal behavior in single-phase flow through rectangular microchannels.
752 citations
TL;DR: In this paper, a hybrid photovoltaic/thermal (PV/T) solar system was designed, fabricated and experimentally investigated in this work, where a parallel array of ducts with inlet/outlet manifold designed for uniform airflow distribution was attached to the back of the PV panel.
622 citations
TL;DR: In this paper, Wang et al. used the Poincare section to analyze the fluid mixing in three-dimensional wavy microchannels with rectangular cross-sections and found that the quantity and the location of the vortices may change along the flow direction, leading to chaotic advection.
423 citations
TL;DR: In this paper, three-dimensional numerical simulations were performed for laminar thermally developing flow in microchannels of different aspect ratios, based on the temperature and heat flux distributions obtained, both the local and average Nusselt numbers were presented graphically as a function of the dimensionless axial distance and channel aspect ratio.
399 citations
TL;DR: In this paper, a simple configuration of oblique cuts across the straight fins of a conventional straight channel design was developed, to enhance the performance of the conventional channel with minimal pressure penalty.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: In this paper, the authors provide a review on two aspects that are battery thermal model development and thermal management strategies, and discuss thermal effects of lithium-ion batteries in terms of thermal runaway and response under cold temperatures.
Abstract: Power train electrification is promoted as a potential alternative to reduce carbon intensity of transportation. Lithium-ion batteries are found to be suitable for hybrid electric vehicles (HEVs) and pure electric vehicles (EVs), and temperature control on lithium batteries is vital for long-term performance and durability. Unfortunately, battery thermal management (BTM) has not been paid close attention partly due to poor understanding of battery thermal behaviour. Cell performance change dramatically with temperature, but it improves with temperature if a suitable operating temperature window is sustained. This paper provides a review on two aspects that are battery thermal model development and thermal management strategies. Thermal effects of lithium-ion batteries in terms of thermal runaway and response under cold temperatures will be studied, and heat generation methods are discussed with aim of performing accurate battery thermal analysis. In addition, current BTM strategies utilised by automotive suppliers will be reviewed to identify the imposing challenges and critical gaps between research and practice. Optimising existing BTMs and exploring new technologies to mitigate battery thermal impacts are required, and efforts in prioritising BTM should be made to improve the temperature uniformity across the battery pack, prolong battery lifespan, and enhance the safety of large packs.
