In this paper, a thorough review of the available literature on solar cookers is presented. The review is performed in a thematic way in order to allow an easier comparison, discussion and evaluation of the findings obtained by researchers, especially on parameters affecting the performance of...

It is well known that accurate knowledge of photovoltaic cell parameters from the measured current–voltage characteristics is of vital importance for the quality control and the performance assessment of photovoltaic cells/modules. Although many attempts have been made so far for a thorough...

The pressure-loss coefficient for a duct junction of square cross-section was determined using computational fluid dynamics (CFD). The predicted junction pressure-loss coefficient for combining flows was generally in good agreement with experimental data from the literature. The junction...

This paper presents measurements and predictions of the pressure-loss coefficient for a wide-angle, three-dimensional diffuser with free discharge. The constant tracer-gas method was used for measuring duct mean velocity, and static pressure tappings for pressure change across the diffuser. The...
