A sort of novel bifunctional microencapsulated phase change material (PCM) was designed by encapsulating n-eicosane into a crystalline titanium dioxide (TiO2) shell and, then, was successfully synthesized through in-situ polycondensation in the sol–gel process using tetrabutyl titanate as a...

The effects of primary steam superheating on steam condensation in nozzle and the performance of steam ejector were investigated using CFD (computational fluid dynamics) method. Using a wet steam model being proposed in our previous study, simulations based on the primary steam with five...

Overwhelming evidence indicates that climate change, caused in large part by human activities, is already adversely impacting all people, with the very real prospect of worse to come. Nevertheless, a global treaty to curb carbon emissions remains elusive. In East Asia, all middle-income...

A sort of new phase change material (PCM) microcapsules based on n-octadecane core and calcium carbonate (CaCO3) shell was synthesized through a self-assembly method to enhance the thermal conductivity and serving durability. Fourier transform infrared spectra confirmed that the CaCO3 wall...

In this paper, non-deterministic CFD (computational fluid dynamics) simulations have been performed to investigate the uncertain effects of stochastic boundary conditions on the aerodynamic performance of wind turbines. A NIPRC (non-intrusive probabilistic collocation) method is employed, which...

A new silica encapsulation technique toward n-octadecane PCM (phase change material) was developed through sol–gel synthesis using sodium silicate as a silica precursor. Fourier transform infrared spectra confirm the chemical composition of the synthesized microcapsules, and wide-angle X-ray...

A series of n-alkanes/silica composites as form-stable phase change materials (PCMs) were synthesized in a sol–gel process using sodium silicate precursor. The chemical compositions and structures of the synthesized composites were characterized by Fourier transform infrared spectroscopy....

This paper considers the design and performance of auction mechanisms used to deploy renewable energy in three emerging economies: Brazil, China, and India. The analysis focuses on the countries'experience in various dimensions, including price reductions, bidding dynamics, coordination with...
