Operation optimization is a critical issue in the management of the multi-source large-scale urban centralized heating system (UCHS). A major challenge is to deal with the complex topological structure of its heating network. We investigate the operation enhancement of UCHS from the view of...

Non-isothermal crystallization of aqueous nanofluids in the presence of two types of high aspect-ratio carbon nano-additives, i.e., carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs), was characterized by means of differential scanning calorimetry (DSC). A parametric investigation was...

The effects of adding various carbon nanofillers on the thermal conductivity and energy storage properties of paraffin-based nanocomposite phase change materials (PCMs) for thermal energy storage were investigated experimentally. These included short and long multi-walled carbon nanotubes,...

The performance of a parabolic trough collector (PTC)-based steam generation system depends significantly on the heat losses of the solar receiver. This paper presents an experimental study of the heat losses of a double glazing vacuum U-type solar receiver mounted in a PTC natural circulation...
