A concept of solar chimney utilizing solar panels for building passive ventilation is proposed in this paper. First, CFD Numerical analyses were conducted to test the feasibility. Major dimensional parameters were considered in the simulation and meaningful air flow rates were observed under normal conditions. Experiments were conducted to confirm the concept and to understand the physical mechanism of the phenomenon by air buoyancy. Based on the results of the study, the proposed solar panel chimney and its advantages are worth of further investigation. Based on this innovative concept, the rooftop solar panel could be re-arranged, grouped and boxed to form an effective solar panel chimney, to serve as passive ventilation system without much cost and fully utilize the solar power.
This study aims to develop an innovative Generator that can be installed in pipelines with ease or even without stopping the fluid flow under certain conditions. The turbine design was the major focus and modern engineering tools such as 3D CAD software and Rapid Prototyping technology were utilized during the development. Designs of different turbine structures were tested and the turbine with swing gates seems to be the best choice in this application. Experiments on parameters such as rotational velocity and voltages were performed with satisfactory results.
