The lithium-ion battery is widely used in the power system of pure electric vehicles and hybrid due to its high energy density. However, chemical electrochemical reactions generate a lot heat. If heat not transferred through some refrigeration methods time, it will lead rapid rise temperature battery. In this paper, an electric–thermal coupling model cylindrical Panasonic 21700 was proposed by using offline parameter identification method. Based on model, thermal management pipe established....
In the current study, dynamic characteristics of droplets impacting a hydrophilic/hydrophobic inclined wall are investigated using front-tracking method. The morphological and kinematic features examined across various contact angles (θ), low Weber numbers (We≤10), inclination (α). A sequence events, including deposition, spreading, contraction, rebound, subsequent re-spreading, is observed when droplet impacts hydrophobic wall, according to results. exhibits both small dimensionless...

Condensation-induced jumping of droplets on superhydrophobic surfaces has received extensive attention because its great potential for applications in areas such as condensation enhancement and self-cleaning. However, the efficiency flat is very low, there no reliable means achieving efficient droplet large scales, which greatly limits application. To this end, we developed a class honeycomb bionic (HBSS) that enable scale first time performed experimental simulation studies kind surface....
