    Preparation, thermal and rheological properties of hybrid nanocomposite phase change material for thermal energy storage
    (Elsevier, 2014-02) Parameshwaran, R.
    This paper presents the experimental investigation on the thermal properties and viscosity of the new organic ester phase change material embedded with the silver–titania hybrid nanocomposite (HyNPCM) with the mass proportions ranging from 0.1% to 1.5%. The HyNPCM embedded with the surface functionalized hybrid nanocomposite exhibited improved thermal conductivity from 0.286 W/m K to 0.538 W/m K, congruent phase change temperature (6.8 °C), high latent heat capacity (90.81 kJ/kg), substantial reduction in the supercooling degree (1.82 °C), thermal stability (191 °C) and chemical stability, while compared to the pure PCM. Experimental results reveal that, the freezing and the melting times of the HyNPCM were reduced by 23.9% and 8.5% respectively, when compared to the pure PCM. The increased mass proportion of HyNC resulted in the increased viscosity up to 3.89%, which suggests the existence of relative dependencies between the thermal properties and the viscosity of the HyNPCM. In total, the improved thermal properties and the heat storage potential of the HyNPCM has facilitated them to be considered as a viable candidate for the cool thermal energy storage applications in buildings without sacrificing energy efficiency.

    Thermal Energy Storage Technologies for Sustainability Systems Design, Assessment and Applications
    (Elsevier, 2014) Parameshwaran, R.
    Thermal Energy Storage Technologies for Sustainability is a broad-based overview describing the state-of-the-art in latent, sensible, and thermo-chemical energy storage systems and their applications across industries. Beginning with a discussion of the efficiency and conservation advantages of balancing energy demand with production, the book goes on to describe current state-of-the art technologies. Not stopping with description, the authors also discuss design, modeling, and simulation of representative systems, and end with several case studies of systems in use.
