Journal ArticleDOI
Thermal-physical properties of nanoparticle-seeded nitrate molten salts
TL;DR: In this article, the authors used a dynamic scanning calorimeter to measure specific heat, latent heat and melting temperature of the nanosalt and nanosalts over a wide range of temperature up to 773 K.
Journal ArticleDOI
Comparative study of the transient natural convection in an underground water pit thermal storage
Chun Chang,Chun Chang,Zhiyong Wu,Helena Navarro,Chuan Li,Guanghui Leng,Xiaoxia Li,Xiaoxia Li,Ming Yang,Zhifeng Wang,Yulong Ding +10 more
TL;DR: In this article, the authors investigated the transient natural convection phenomenon in an underground water pit thermal storage with heat losses through the surrounding walls, and a numerical model was developed to obtain the characteristics of the thermal stratification in the water pit.
Journal ArticleDOI
Development of MIL-101(Cr)/GrO composites for adsorption heat pump applications
Eman Elsayed,Haiyan Wang,Haiyan Wang,Paul A. Anderson,Raya Al-Dadah,Saad Mahmoud,Helena Navarro,Yulong Ding,James Bowen +8 more
TL;DR: In this article, the enhancement of the thermal conductivity and water adsorption characteristics of MIL-101(Cr) using hydrophilic graphene oxide was investigated, and two methods have been used to develop MIL- 101(Cr)/GrO composites.
Journal ArticleDOI
Rheology of Solar-Salt based nanofluids for concentrated solar power. Influence of the salt purity, nanoparticle concentration, temperature and rheometer geometry
Belén Muñoz-Sánchez,Javier Nieto-Maestre,Elisabetta Veca,Raffaele Liberatore,Salvatore Sau,Helena Navarro,Yulong Ding,Nuria Navarrete,J. Enrique Julia,Ángel G. Fernández,Ana García-Romero +10 more
TL;DR: In this article, the influence of the nanoparticle concentration on the viscosity of the refined grade solar salt is analyzed according to the Maron-Pierce and Kriegher-Dougherty models for the nanofluids containing alumina and silica nanoparticles respectively, due to their different shape.
Journal ArticleDOI
Evaluation of new pcm/pv configurations for electrical energy efficiency improvement through thermal management of pv systems
TL;DR: In this paper, the authors investigated several system configurations and different phase change materials (PCM) and compared the system with and without insulation through computational fluid dynamic (CFD) tools, and the final goal is to optimise and control the temperature of PV modules and evaluate their system efficiency and energy generation.
