Ocean wave energy is one of the world's most powerful forms of energy and the energy density in ocean waves is the highest among renewable energy sources. Wave energy converters are employed to harness this energy and convert it into usable electrical energy. However, in order to efficiently...

Following the detailed study of the three modules of the Solar Multiple Condensation Evaporation Cycle (SMCEC)-based desalination unit located in Sfax, Tunisia, it was found necessary to couple the three modules, to simulate the desalination unit operation in an environment close to that of the...

This paper reports a procedure to optimise district heating networks on the basis of second law analysis. The approach is derived from the exergonomic theory. A cost function has been set up and an iterative procedure was employed to determine the minimum value corresponding to the optimal pipe...

This paper addresses the dimensional analysis of experimental data for the impulse turbine and the use of that data to create a model to predict the performance characteristics of any size of turbine under a range operating conditions. The model assumes that the performance of the turbine is a...

This study demonstrates a direct transesterification (DT) method for reliable quantification of microalgal lipid. Primary screening of various transesterification methods and the types of biomass (wet, oven dried and lyophilized) were performed with heterotrophically grown Chlorella sp. FC2 IITG...

A proposal for an extended formulation of the power coefficient of a wind turbine is presented. This new formulation is a generalization of the Betz–Lanchester expression for the power coefficient as function of the axial deceleration of the wind speed provoked by the wind turbine in...

The need for new sources of renewable energies and the rising price of fossil fuels have induced the hope that agricultural crops may be a source of renewable energy for the future. We question in this paper the best strategies to convert solar radiation into both energy and food. The intrinsic...

A solar tunnel drier is optimised for drying of chilli in Bangladesh. The simulation model was combined with the economic model of the solar tunnel drier and adaptive pattern search was used to find the optimum dimensions of the collector and the drying unit. Two optimum designs are obtained....
