The paper presents a new concept of building integrated thermal energy storage unit and novel mathematical and numerical models of its operation. This building element is made of gypsum based composite with microencapsulated PCM. The proposed heat storage unit has a form of a ceiling panel with...

Nonlinear effects in the two-component medium with conductivities σ1 (metal) and σ2 (insulator) near the percolations threshold is studied. For the medium having cubic nonlinearity an effective nonlinear conductivity ae and correlation functions of the electrical field 〈e4〉 and current...

A numerical model for the vertical profile of aeolian mass flux was established based on the launch velocity probability distribution of saltating sand particles. The mean launch velocity (v̄0) was used as a primary variable in the simulation, from which the average saltation height and length...

This paper concerns heat exchange devices with a zigzag configuration containing multi-phase change materials (m-PCMs). A two dimensional mathematical model was established to model the charging behaviour. An experimental system was built to validate the model. The modelling results agree...
