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...

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...

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...

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...

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...

This paper investigates a few mathematical aspects of computer simulation of salt gradient solar pond’s thermal behavior. The basic equation governing heat flow in the non-convective zone of solar pond is solved by finite difference approach using the Crank–Nicholsen method. Stability and...
