Title: Thermal conduction with phase change in a cylindrical liquid-solid two phase system under non-axisymmetric condition
Authors: Jicheng Guo, Mustafa Ordu, James Bird, Soumendra Basu,
Abstract: The melting dynamics of a phase change material (PCM) under non-axisymmetric condition appear qualitatively similar to the evaporation of a drop under Leidenfrost conditions, as both features a thin liquid/vapor layer between PCM and hot surface. However, the extent of the analogy is unclear. Here, we investigate the melting dynamics of PCM in thin-walled cylindrical containers. Through a combination of experiments and physical modeling, we identify a characteristic melting time and gap thickness, which we compare to evaporating droplets.

Abstract: Design and construction of transparent electrodynamic screens(EDS) printed on ultra thin(100μm) flexible Corning®WillowTM glass film for retrofitting on solar mirrors and panels providing self-cleaning function are presented. Large-scale solarplants installed in semi-arid and desert lands can be shielded by EDS from dust layer build upon solar collectors, which cause major energy-yield loss[1,2]. Cost-effective printing of transparent conductive electrodes is discussed.
