Facilitating Large-Scale Snow Shedding from In-Field Solar Arrays using Icephobic Surfaces with Low-Interfacial Toughness

Abhishek Dhyani et al.

Summary: The study developed a surface structure with low interfacial strength and high toughness, enabling passive shedding of snow and ice, suitable for applications in solar arrays and automotive windshields. These transparent, easily scalable surfaces can significantly increase power generation in subzero temperatures, making them ideal for areas with persistent snow accumulation.

A diffusion-enhancing icing theory for the freezing transition of supercooled large water droplet in impact

Weiliang Kong et al.

Summary: This paper investigates the impact and freezing behavior of supercooled water droplets on inclined surfaces through experimental and theoretical studies. The results show that different freezing morphologies and a piecewise nonlinear supercooling-freezing time relation can be observed under different supercoolings. The dynamics-icing interaction increases the heat conduction area in higher supercooling, leading to enhanced freezing rate. A diffusion-enhancing icing theory is proposed, which provides better predictions for the freezing rate of impinging supercooled water droplets, especially in conditions of high supercooling and hydrophobic surface.

Self-peeling of frozen water droplets upon impacting a cold surface

Wen-Zhen Fang et al.

Summary: This study reports a passive ice removal method by utilizing the thermal-mechanical stress of ice for the self-peeling of frozen water droplets upon impacting a cold substrate. The study found that the frozen ice can completely self-peel and be easily removed from a cold hydrophobic surface, while it exhibits cracking and remains firmly sticky to a hydrophilic surface. Experimental and theoretical investigations were conducted to analyze the peeling behaviors of frozen water droplets and a simple criterion for predicting complete self-peeling was proposed to facilitate the design of anti-icing surfaces.

Effect of asymmetric cooling of sessile droplets on orientation of the freezing tip

Anton Starostin et al.

Summary: The shape of the freezing tip formed by water droplet crystallization shows universality and is not affected by cooling rate or substrate properties. The orientation of the freezing cone can vary, possibly due to changes in the direction of heat flux.

Droplet impacts on cold surfaces

B. Gorin et al.

Summary: This study investigates the impact of cooled liquid droplets on surfaces. The freezing process affects the spreading dynamics and surface coverage of the droplets. Experimental observations and a freezing model reveal that droplet arrest occurs when a solid layer of the liquid forms on the substrate, and a simple model can efficiently predict the maximum spreading diameter of droplets at different impact velocities and surface temperatures below the freezing point.

Experimental Study on Solidification Characteristics of Sessile Urine Droplets on a Horizontal Cold Plate Surface under Natural Convection

Qun Dang et al.

Summary: Urine, as a test material in medical research, can reflect the health status of the body directly. This study experimentally investigated the solidification characteristics of urine droplets on a horizontal cold plate surface under natural convection, and compared them with water droplets. It was found that the solidification process of a urine droplet goes through four stages: supercooling, recalescence, freezing, and cooling. Additionally, the urine droplet changes color from transparent to blur white at the supercooling stage due to the precipitation of inorganic salts. The results of this study are expected to provide references for urinalysis of patients with metabolic diseases.

Modelling study on freezing process of water droplet on inclined cold plate surface with droplet dynamic behavior considered

Qun Dang et al.

Summary: This study presents a theoretical model based on the heat-enthalpy method to predict and control the freezing process of water droplets on inclined surfaces. The research analyzed the freezing characteristics of water droplets on inclined surfaces and found that the inclined angle has a greater impact on smaller droplets compared to larger droplets. This study is beneficial for optimizing anti-frosting and defrosting technologies.

Ultra-low ice-substrate adhesion and self-deicing during droplet impact freezing

Puhang Jin et al.

Summary: When a water droplet freezes on a supercooled surface, it usually adheres to the substrate. However, our study shows that water droplets freezing on medium to high supercooled copper surfaces exhibit ultra-low ice-substrate adhesion and remarkable self-deicing. We found that the adhesion is controlled by the mechano-thermo-hydraulic coupling during droplet-impact freezing, which reduces the droplet-substrate contact and enables self-peeling due to thermal-mechanical stress relaxation.

Freezing morphologies of impact water droplets on an inclined subcooled surface

Fang-Qi Zhu et al.

Summary: The study investigates how the frozen morphologies of impact water droplets are formed on a subcooled inclined surface. Four types of frozen droplet morphologies were discovered, and a phase diagram was proposed to show how frozen morphologies are controlled by droplet impact and freezing related timescales. The competition between droplet solidification and impact hydrodynamics timescales are altered by the inclined impact.

How different freezing morphologies of impacting droplets form

Summary: This study investigates the interaction between droplet spreading and solidification in impacting water droplets, and demonstrates that freezing morphologies depend on the impact velocity and substrate temperature. Competitive timescales play a significant role in determining the formation of different morphologies.
