This article uses TM images in 1999 and 2006 in Dahua County, selects the driving factors having great impact on urban land use change, and conducts data processing using GIS software. It then uses CLUE-S model to simulate land use change pattern in 2006, and uses land use map in 2006 to test...

Dynamic simulation, design improvements and control issues in solar power plants might compete with special considerations on energy storing techniques. In order to provide the stability in production of power or chemical commodities in spite of discontinuity in the source of energy, i.e., sun,...

This study investigates the impact of the design of a heat recovery steam generator (HRSG) on its dynamic behaviour under the boundary condition of a gas turbine start-up. For that purpose, a validated HRSG model with three pressure stages and reheater section is modified by replacing the...

High CO2 purity products can be obtained from oxy-combustion power plants through a CO2 CPU (compression and purification unit) based on phase separation method. To ensure that CPU (with double flash separators) can be operated under optimal conditions, this paper focuses on single variable...

In the paper it has been analyzed specific character of building economy; developed a model of branch forecasting, forecast of construction branch in Latvia. The model consists of two parts: formation of demand and supply. The basic role belongs to demand forecasting. Demand form three...

This paper presents a dynamic simulation model and a parametric analysis of a solar-geothermal hybrid cogeneration plant based on an Organic Rankine Cycle (ORC) powered by a medium-enthalpy geothermal resource and a Parabolic Trough Collector solar field. The fluid temperature supplying heat to...

The European Energy Efficiency Building Directive 2002/91/CE, as well as other acts and funding programs, strongly promotes the adoption of passive strategies for buildings, in order to achieve indoor thermal comfort conditions above all in summer, so reducing or avoiding the use of air...

In northern Algeria, use of ventilation by ceiling fans is widespread in mosques and other public buildings during the hot season, but is seldom used in private houses. In the first part of this study, the impact of this mode of cooling on indoor thermal comfort is investigated. A thermal...

In this paper an integrated fuel cell/household model is developed in order to assess the capability of fuel cells to fulfil different tasks in the energy market. The dynamic properties of two stationary combined heat and power (CHP) fuel cell systems were determined experimentally and serve as...

The desiccant wheel is a key component of open desiccant air-conditioning systems. Development of a simplified method of assessing their dynamic performance would assist the growth of the industry. Important errors can occur when constant values of the effectiveness parameters are assumed in the...
