The receiver thermal performance directly affects the efficiency, reliability and safety of the entire solar tower power system. A model combining radiation, convection and conduction heat transfer modes was developed to model a 1 MW molten salt cavity receiver with determined basic design...

An experimental platform was designed and built for testing the thermal performance of a water/steam cavity receiver. The experimental platform was utilized to investigate the start-up performance and operation characteristics of the receiver. The electrical heating mode was chosen to simulate...

Recent time has witnessed severe scarcity of water owing to deficient rainfall in India. The current climatic conditions in the country, project the rise in temperature and arid conditions contributing substantially towards the evaporation losses. In order to deal with the looming crisis, it is...

The role of microphysical effects in the ability of a small new phase nucleus to emit molecules into the vapor is revealed on a thermodynamic basis. It is shown that dependence of the surface tension of a nucleus on its temperature and the dependence of the vaporisation heat on the nuclear...

A novel linear Fresnel reflector which employs the evacuated tube, CPC secondary reflector, and uses molten salt as the heat transfer fluid (HTF) was designed and studied in this paper. A 3D optical model was developed to simulate the radiation transmission within the system with Monte Carlo Ray...

A state-of-the-art solar crop dryer was developed with thermal energy storage to maintain continuity of drying of herbs for their colour and flavour vulnerability. The dryer consists of flat plate solar collector, packed bed phase change energy storage, drying plenum with crop trays and natural...

This paper studied the thermal and power performances of a ventilated photovoltaic façade under different ventilation modes, and appropriate operation strategies for different weather conditions were proposed accordingly to maximize its energy conversion efficiency. This ventilated PV...

Structural–functional integrated materials are one of directions of rapid development for saving-energy materials. Phase Change Materials (PCMs) are latent thermal storage materials possessing a large amount of heat energy stored during its phase change stage. Porous lightweight aggregate...

The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof...

In recent years there has been a growing interest in the development and thermal-energy analysis of passive solutions for reducing building cooling needs and thus improving indoor thermal comfort conditions. In this view, several studies were carried out about cool roofs and cool coatings,...
