Basic Solar Chimney Flow Improvements

Preliminary note This paper deals with the numerical analysis procedure and results of flow simulation through solar chimney. Because of relatively low Reynolds numbers, some aerodynamic improvements could be obtained. The paper links input heat energy with geometry or air flow parameters. Basic solar chimney geometry is carried out and analyzed with CFD application in three dimensional domain....

Measuring Velocity Changes along a Solar Chimney

The increasing consumption of energy from fossil fuels on the one hand and the pollution created by it on the other hand has always raised the concern of replacing clean and renewable energy with fossil fuels in the human mind. Generating electricity through clean energy can be a good solution to reduce pollutants and prevent global warming. One of the most available types of renewable energy i...

This paper presents an architectural framework, which identiies the core services necessary for a secure Internet-based communication and information infrastructure. We show how these services can be realized using existing software packages and new technologies. Then, we turn to the development of security infrastructures using the rapid prototyping environment \Wafe" and the extensible Web br...

We describe our experience in designing object-oriented software for a sparse direct solver. We discuss , a library of sparse matrix ordering codes and Oblio, a code implementing the remaining steps in a direct solver. EEciencies comparable to procedural codes are obtained by careful implementations of eecient algorithms. We discuss the other goals of our design: managing complexity, simplicity...
