Wind conditions in the built environment are complex in nature and characterized by lower wind speeds and higher turbulence due to the presence of obstructions. A growing body of literature and research testing activities related to performance evaluation of small wind turbines (SWTs) in urban wind conditions have inferred that …

While not fully predictive. the model is considered to be accurate enough for design purposes. With the model at hand. the suitability of various combinations of greenhouse plastic and honeycomb designs can be assessed. It should be noted that the model predicts a heat transfer coefficient of 4.25 W m …

This paper. like the title suggest. has presented a brief overview about biodiesel from microalgae focused in biorefinery concept. It has been exposed some alternatives that can help to reduce the high cost of biodiesel production based in microalgae. turn it more feasible. It has become clear that when it …

As demonstrated here. microalgal biodiesel is technically feasible. It is the only renewable biodiesel that can potentially completely displace liquid fuels derived from petroleum. Economics of producing microalgal biodiesel need to improve substantially to make it competitive with petrodiesel. but the level of improvement necessary appears to be attainable. Producing …

Analysis and Design of Energy Geostructures gathers for the first time theoretical. experimental and design knowledge available to date about energy geostructures: an innovative technology that couples for any type of built environment the structural support role of the geostructures with the heating-cooling role of the geothermal heat exchangers harvesting …

The microalgae are considered as one of the most promising feedstocks for future bio-diesel production in India. The advantages of microalgae are their widespread availability. higher oil yields and reduced pressure on cultivable land. The difficulty in efficient biodiesel production from algae lies not only in the extraction of the …

This paper has analyzed the impact of large induction motors on the dynamic performance of distribution networks in the presence of a wind farm. The study is restricted to wind farms with small installed capacity compared to the local industrial plants. The results show that the technology of the wind …

The following conclusions can be drawn from the present study: The increase in alcohol content in diesel or biodiesel fuels always led to an increase in both IDCF and IDM. Such an increase was sharper at high alcohol contents. This implies that weight or volume averaging of autoignition parameters (such …

This book explores the electric railway systems that play a crucial role in the mitigation of congestion and pollution caused by road traffic. It is divided into two parts: the first covering fixed power supply systems. and the second concerning the systems for railway rolling stock. In particular. after a …

Novel underground well pattern systems. replacing fracturing reservoir with horizontal wells. were proposed for geothermal energy exploitation in this paper. The most important feature of the well pattern systems was the wholly closed circulation inside the wellbores. Compared to the fractured reservoir system where the fluid flowed in the porous …
