An Experimental Investigation of a Solar Chimney Natural Ventilation System
Cold Inflow-Free Solar Chimney
Author: Md. Mizanur Rahman
Publisher: Springer Nature
ISBN: 9813368314
Category : Technology & Engineering
Languages : en
Pages : 244
Book Description
This book highlights the design of a new type of solar chimney that has lower height and bigger diameter, and discusses its applications. The bigger diameter chimneys are introduced showing cold inflow phenomena that significantly reduced the performance of solar chimney. The cold inflow-free operation of solar chimneys restores the draft losses and enhances the performance of the solar chimneys. Numerical and experimental investigation results will be presented to highlight the performance of cold inflow-free solar chimney performance. In addition, this book covers the important basic design parameters that affect the design of solar chimney for different applications, mainly, solar chimney-assisted ventilation for passive cooling and power generation system.

Induced Flow for Ventilation and Cooling by a Solar Chimney
Author: Ahmed Abdulnabi Imran
Publisher: LAP Lambert Academic Publishing
ISBN: 9783659509858

Languages : en
Pages : 184
Book Description
Energy consumption in the building sector is clearly an important factor in the total energy bill, and it continues to increase. Cooling and heating in buildings are techniques used to condition their environments, research and development of natural methods for this conditioning are assumed to increase the importance in modern building in order to bring about savings in energy. Depletion of the world fossil fuel reserves and price uncertainty has forced many countries to turn to alternative energy sources to meet their needs. Like many other countries, Iraq, despite its oil wealth, must take steps in studying and utilizing alternative energy sources. Solar energy is one of the potential alternative energy sources, is particularly attractive because it is renewable, nonpolluting and widely available on-site. Solar energy is being used for many purposes, such as electricity generation, refrigeration and air-conditioning applications. Solar chimneys are one kind of renewable energy technologies, which enhance the natural ventilation of buildings.

An Experimental Study Into the Operation of a Solar Chimney Used for the Improvement of Natural Ventilation in Buildings
An Experimental Investigation of a Solar Chimney Model with Uniform Wall Heat Flux
An Introduction to Uncertainty in Measurement
Author: L. Kirkup
Publisher: Cambridge University Press
ISBN: 1139454900
Category : Science
Languages : en
Pages : 196
Book Description
Measurement shapes scientific theories, characterises improvements in manufacturing processes and promotes efficient commerce. In concert with measurement is uncertainty, and students in science and engineering need to identify and quantify uncertainties in the measurements they make. This book introduces measurement and uncertainty to second and third year students of science and engineering. Its approach relies on the internationally recognised and recommended guidelines for calculating and expressing uncertainty (known by the acronym GUM). The statistics underpinning the methods are considered and worked examples and exercises are spread throughout the text. Detailed case studies based on typical undergraduate experiments are included to reinforce the principles described in the book. This guide is also useful to professionals in industry who are expected to know the contemporary methods in this increasingly important area. Additional online resources are available to support the book at www.cambridge.org/9780521605793.

Evaluation of the Potential of Solar Chimneys to Drive Natural Ventilation in Non Domestic Buildings

Book Description
The solar chimney allows natural ventilation to be achieved during periods when the wind velocities are low and the difference between internal and external air temperatures is minimal. The correct design of such building components requires that designers have appropriate design tools available to them that are both effective and easy to use. The aim of this project was to evaluate design tools currently available and if appropriate to provide a tool that would allow the effects of variations in key physical parameters to be evaluated. Two design tools are currently available to designers; zonal models and CFD programmes. Both of these were however found to be unsuitable for the evaluation of the performance of a solar chimney. Zonal models assume that the air within a zone is fully mixed which results in the effects of variations in physical parameters on the mass flow rate being incorrectly predicted. CFD programmes require validation of any models developed before confidence in the predictions can be established, it was found however that data for such validation was not available for realistic flow configurations. An experimental rig was designed and tested to ensure that the uncertainty in the data produced was both minimised and accurately quantified. A detailed review of the sensitivity of a CFD programme to model and input variables was undertaken allowing development of an appropriate model. Comparison of the results of the experimental investigation and CFD predictions showed that the CFD programme, utilising the ke turbulence model accurately predicted air flow rates through a solar chimney across a range of key physical parameter variations. Within the limits of the validity determined for the CFD model, a detailed parametric investigation was then undertaken. The result of the parametric investigation was the development of a design tool appropriate for the determination of the effects of variations of the key physical variables on the mass flow rate t.
