If renewable energy sources are to be successfully utilised within the built environment then accurate simulation tools have an important role to play. This paper addresses a very specific part of the overall simulation process: that of earth-contact heat transfer which can be the cause of...

The aerodynamic characteristics of wind turbines are closely related to the geometry of their blades. The innovation and the technological development of wind turbine blades can be centred on two tendencies. The first is to improve the shape of existing blades; the second is to design new shapes...

Electrocoagulation process (EC) was performed in an upflow blanket reactor (UBR) applying response surface methodology (RSM) based on the Box–Behnken design (BBD) to produce hydrogen gas and reduce the chemical oxygen demand (COD) from chicken industry wastewater. The results showed that RSM...

A study on the effect of different device parameters on the photophysical and photovoltaic behavior of thin-film luminescent solar concentrators (LSCs) is presented in this work. The concentration of the luminescent species, the thickness of the LSC film, the geometric gain of the LSC device and...

This work investigated the potential of shea butter oil (SBO) as feedstock for synthesis of biodiesel. Due to high free fatty acid (FFA) of SBO used, response surface methodology (RSM) was employed to model and optimize the pretreatment step while its conversion to biodiesel was modeled and...

Photovoltaic thermal (PV/T) air collector design requires an accurate determination of key parameters such as the channel depth and the air mass flow rate. This paper focuses on PV/T air collectors linked to an air distribution system with the aim of optimizing the channel depth, the air mass...

Due to rapid depletion of the fossil fuel reserves and environmental concerns biodiesel has attracted a great deal of attention over the last few decades. In this study, heterogeneous catalysts derived from waste chicken bones were employed in the transesterification reaction of waste cooking...
