    Abstract: In this paper, a time stepping 2D and 3D FEM is performed for modeling and analysis external rotor DFIG .The finite element method currently represents the state-of-the-art in the numerical magnetic field computation relating to electrical machines. FEM is a numerical method to solve the partial differential equations (PDE) that expresses the physi... Show More

    Abstract: Solar radiation is the main energy source and responsible for heat gain in buildings, particularly in tropical climate regions. In general, roofing is one of the constructive components that receive most of incident solar radiation in single-storey buildings. One of the techniques to attenuate the solar heat gain is the use of radiant barrier in th... Show More

    Abstract: In the present work, experimental investigation on the dynamic performance of sealed and less maintenance vertical packed porous bed desiccant dehumidification system has been carried out. The desiccant bed operates as an adsorber and then operates as a regenerator intermittently. In the experimental part of this investigation, silica gel is applie... Show More
