Stability of salt gradient solar pond salinity profile is examined under transient thermal phase. The analysis is done for straight as well as parabolic salinity profile. It is observed that the stability criterion at the upper interface of salinity profile is satisfied for a thin non-convective...

In case of noninsulated salt gradient solar pond, heat losses through bottom and sides are significant. The magnitude of losses depends upon the location (depth) of water table, which act as a heat sink. Simulation analysis indicates that deeper the water table, lesser are the heat losses and...

Using low-pressure chemical vapour deposition (LPCVD), multi-walled carbon nanotubes (MWNTs) are grown on nanocrystalline Fe<Subscript>70</Subscript>Pt<Subscript>30</Subscript> film. The Fe<Subscript>70</Subscript>Pt<Subscript>30</Subscript> nanocrystalline film is deposited by vapour condensation technique. The size of the nanoparticles varies from 5–10 nm, as inferred from SEM...</subscript></subscript></subscript></subscript>

Nanoscale synthesis of silver sensitized titanium vanadium mixed-metal (Ag/TiV) oxides was done employing sol–gel technique. The physico–chemical properties of the material were examined using XRD (X-ray diffraction), SEM (Scanning Electron Microscopy), EDAX (Energy Dispersive X-ray...

This paper proposes a common performance parameter for different solar cooker types in place of different performance parameters hitherto being used for each type. The performance parameter called cooker opto-thermal ratio (COR) is based on the Hottel–Whillier–Bliss (HWB) equation and may be...

One of the many thermal performance parameters such as efficiency, cooking power, figures of merit etc. are used to evaluate a solar cooker (including box type) based on test procedures which are non-identical. In the absence of an interrelation between the different performance parameters, it...

In this paper we discuss issues involving energy security with economic growth and development that brings out (i) the dimension of physical security alternative, (ii) framework for a pan South East Asian platform to support energy security and (iii) requirement of promoting regional energy...
