Community-scale power infrastructure may be the only electrification option for tens of millions households that remain out of reach from centralized power grids. The responsiveness of household electricity demand to price is a crucial design input for off-grid systems. While the price...

Random digit dialed telephone surveys are facing two serious problems undermining probability-based inference and creating a potential for bias in survey estimates: declining response rates and declining coverage of the landline telephone frame. Optimum survey designs need to focus reduction...

An unsteady two phase nonisothermal model is used to study the start-up characteristics of a polymer electrolyte membrane fuel cell (PEMFC). The model is 3D in nature and a PEMFC with serpentine flow field and 9 channels is simulated. The base case is run with equilibrium or inflow initial...

This study presents the advances in plate heat exchangers both in theory and application. It dresses the direction of various technical research and developments in the field of energy handling and conservation. The selected areas of heat transfer performance and pressure drop characteristics,...

There is great potential for the expansion of the small or micro scale hydropower network. Of the 43 thousand weirs in the UK there are only 500 consented hydro schemes. Planning applications for such schemes require a noise assessment. Noise evaluation of a proposed renewable scheme is often...

This paper is the first of three, which outline the procedures and results for a set of experiments carried out on various configurations of the Transverse Horizontal Axis Water Turbine (THAWT), which is a horizontally orientated variant of the Darrieus cross-flow turbine. Tests were conducted...
