“…Reference [25] researches showed that during the melting process of the snow layer on the surface of the PV module, the LWC at the bottom would gradually increase, and the slush layer plays a good role in lubrication, which will promote the snow layer to slide from the surface of the PV module. Reference [17] and [20] carried out the snow melting experiment through electric heating and found that the melted water at the bottom was absorbed by the surrounding snow layer and may overflow along the bottom edge after saturation, and then the snow will fall off quickly.…”

“…Therefore, researchers worldwide have conducted many studies on the ablation mechanism of snow, the power generation efficiency of PV modules and the snow removal methods. Based on artificial deicing, some schemes have been proposed to improve the anti-ice and snow effect of the PV power station, such as enhancing hydrophobic materials [5,[12][13][14][15][16], increasing the angle of the PV module, spraying snow remover [5,6,12,13], hot water, selfheating [17][18][19][20][21] and other methods. However, the above solutions have certain drawbacks regarding cost, environmental protection, and module destructiveness, and are suitable only for small areas of some PV power stations.…”

The accumulation of snow is one of the essential reasons for the significant decrease in the power generation efficiency of PV stations in winter. For this reason, this paper firstly provides a detailed review of the current research into the physical processes and shedding reasons for the natural melting of snow on PV module surfaces. Then, several common techniques to promote snow and ice melting on PV surfaces are discussed, and the feasibility and shortcoming of ultrasonic technology in removing high‐density snow and ice are analyzed in detail. Finally, this paper proposes two snow sensing technologies for PV modules, namely, image processing method and interdigital capacitance method. Among them, the image method based on fixed camera and UAV detection is more suitable for wide area PV power stations, while the interdigital capacitance method is helpful in obtaining snow characteristic parameters, such as icing type and LWC. The relevant research has certain reference significance for PV power stations to formulate a more reasonable snow removal plan and power generation forecast. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

“…Multiple heat source systems also exist in other domains: the geothermal heat exchangers [16,17,18,19,20,21], the winding heads of electric machines [22,23] and other specific systems such as the heated pavement system to de-ice an airfield runway [24,25]. These multiple heat source issues can be solved using numerical methods like the Finite Element Methods.…”

The challenges of improving wiring harness designs in automotive, aerospace or transport fields are safety, ecology, weight, and cost. To this end, harnesses require superior thermal management, which involves considering several thermal sources with an uncontrolled layout. To date, the primary methods employed for thermal resolution are based on commercial softwares with meshing capabilities because evaluating temperature evolution influenced by several sources in an uncontrolled wire layout is difficult. This study presents a faster alternative method in which an equation based on the Infinite Line Source (ILS) model is used to create a nodal network. A more efficient matrix mathematical application is adapted to solve faster the ILS model. The ILS model relies on a fully connected node network. The wire bundle is a complex system with a variable environment and an uncontrolled wire layout. This work improves and adapts a fast mathematical model to complex geometries. Thus, the adaptation required by the model involves many assumptions. This new approach was tested on 2-wire and 10-wire layouts and then compared with results obtained by using a commercial software: Ansys Fluent. Some gaps exist between these methods. We propose a corrective model that uses equivalent conductivity to solve that issue.

“…Compared with common heating system, the heating efficiency was higher which was 55%. Heymsfield et al [16] designed an anti-ice system based on heating wires and renewable energy. Compared to the de-icing system, this system consumed less energy, and it was not influenced by various weather conditions.…”

In this paper, the effect of different forms of electric heating wire forms on the anti-icing performance of the refrigerated container was studied based on numerical simulation. The heat transfer and the thermal conductivity of the refrigerated container door wall, and the uniformity of airflow distribution in the refrigerated container are analyzed. The heating wire form 2 has the best anti-icing performance and meets the anti-icing requirement When the thermal conductivity is from 0.005 W/(m?K) to 0.01 W/(m?K). The electric heating wires nearest to the inner wall surface is the optimal anti-icing solution. The spare electric heating wires placement can be determined according to the thickness of the refrigerated container door. The specific layout of electric heating wires in the future can be further optimized in combination with carbon emissions.
