The energy conversion units and storage equipment connected to the multi-energy system are becoming diversified, uncertain factors brought by distributed wind power photovoltaic generation make flow structure more complex, which brings great difficulties modeling application of traditional hub methods. This study deeply analyzes coupling operation mechanism systems, carries out calculation anal...

At present, papers concerning energy consumption and forecasting are predominantly dedicated to various known techniques their combinations. On the other hand, research on load modeling methodologies is quite limited. This paper presents a new approach hourly using multivariate linear regression model. The proposed technique provides way accurately model day-to-day just few selected variables. ...

Building energy performance evaluation, as an important process in a sustainable building design, has consequences for global conservation and environmental protection. The traditional methods to perform this evaluation are usually time-consuming computationally complex, have high requirements designers’ professional knowledge on architectural physics software operation skills. To solve these p...

Recently the stepped spillways have been used as an appropriate solution for energy dissipation. In the present study, Siahbisheh dam spillway is simulated by using Computational Fluid Dynamic (CFD), in which the Mixture method and Reynolds Stresses Model (RSM) turbulence model is used. In the first modeling series the over all steppes slope is constant. The number of the steps is increased to ...

In order to obtain the best performance of the solar air heaters, it is necessary to find optimum performance conditions. The aim of this research paper is to achieve optimum conditions, by comparing single and double pass solar air heaters. Also, a brief review study of various related research works of all scenarios for a single and double pass and packed bed (including particle technologies)...
