Based on statistical data of National Statistical Bureau of China, and giving the least-squares fitting of Chebyshev polynomial, the data of electricity consumption in per capita from 1983 to 2013 is analyzed by GM (1,1) method and Chebyshev polynomial least squares method respectively. The results showed...

The long-term uncertainty of offshore wind energy resource in Sansha sea area was studied using the 24-year (January 1st, 1988-December 31st,2011) CCMP (cross-calibrated, multi-platform) wind field data with spatial and temporal resolutions of 0.25°×0.25° and 6 h, respectively. In this paper, three kinds...

By analyzing the potential influence of the operation of multiple wind turbines on the surface boundary layer was studied. Gambit software was used to establish multiple wind turbine and wind field model, and the Fluent software was used to simulate the flow of four sets of wind turbine in parallel and...

Sewage sludge contains large amounts of energy and gasification of sewage sludge may be one of the promising sustainable approaches for hydrogen-rich syngas production from sewage sludge. However, raw sludge is unsuitable for direct gasification and thus pretreatment is necessary to improve its fuel...

This paper put forward economy-energy-environmental model system, set up two scenarios (baseline scenario and new urbanization scenario), analyzed...

Energy harvesting from ambient energy sources has been receiving considerable interest as the power supply of wireless sensors networks. In this paper, a hybrid energy harvester based on magnetic levitation is presented for scavenging power-frequency magnetic field and mechanical energy. A Halbach array...

We present an effective optimal adjustment test method for SCR denitrification device. The decrease of catalyst activity in local regions can lead to non-uniformity of NOx concentration and augmentation of slipped ammonia around outlet of SCR device. In this case, we introduce a two-step adaptive adjustment...
