The storage of thermal energy in a trapezoidal aluminum enclosure via melting PCM phase change material is studied. Experimental observations and numerical simulation are made to examine the process for paraffin wax. development LHTES: latent heat system promising alternate option manage growing imbalance consumption supply. Successive Rubitherm-RT35 designed when it heated from one side frame ...

We present results of a hybrid experimental and theoretical investigation of the fracture scaling in scratch tests and show that scratching is a fracture dominated process. Validated for paraffin wax, cement paste, Jurassic limestone and steel, we derive a model that provides a quantitative means to relate quantities measured in scratch tests to fracture properties of materials at multiple scal...

This paper reviews the stability, heat transfer efficiency and photothermal conversion optimization studies of solid-liquid phase change materials applied to water heaters. Suggestions prospects were proposed. The study shows that PCMs are mostly filled in tank, thermal storage devices or solar collector heater system with paraffin wax, addition can significantly improve performance. Further in...
