This book delves into the design of a novel solar chimney, featuring a lower height and a larger diameter, and explores its various applications. The introduction of larger diameter chimneys highlights the occurrence of cold inflow phenomena, which significantly diminish the performance of solar chimneys. However, the implementation of cold inflow-free operation in solar chimneys restores draft losses and enhances their performance. Comprehensive numerical and experimental investigation results will be presented to showcase the remarkable performance of cold inflow-free solar chimneys. Furthermore, this book encompasses the crucial basic design parameters that influence the design of solar chimneys for diverse applications, primarily focusing on solar chimney-assisted ventilation for passive cooling and power generation systems.

Introduction:
Solar chimneys are a passive cooling and ventilation system that utilizes solar radiation to induce air movement, resulting in temperature reduction and improved indoor comfort. With their simple design and low maintenance requirements, solar chimneys have gained widespread popularity in various applications, including buildings, industries, and agricultural settings. However, the design of solar chimneys is still a challenging task due to the complex interactions between solar radiation, air flow, and thermal properties of the chimney structure.
Lower Height and Larger Diameter Solar Chimney Design:
One of the key challenges in solar chimney design is achieving a balance between a lower height and a larger diameter. A lower height is desirable to minimize the visual impact and reduce the cost of construction, while a larger diameter is necessary to maximize the solar radiation capture and enhance the air flow. In this book, we will explore the design of a new type of solar chimney that has a lower height and a bigger diameter, and discuss its applications.
Cold Inflow Phenomena:
One of the challenges associated with larger diameter solar chimneys is the occurrence of cold inflow phenomena. Cold inflow occurs when cold air enters the chimney from the surrounding environment, reducing the temperature of the air inside the chimney and reducing the overall performance of the system. This phenomenon can significantly diminish the efficiency of solar chimneys, especially in cold climates.
Cold Inflow-Free Solar Chimney Performance:
To address the issue of cold inflow, researchers have developed cold inflow-free solar chimneys. Cold inflow-free solar chimneys utilize a combination of design features, such as adjustable vents, to prevent cold air from entering the chimney. By maintaining a constant temperature inside the chimney, cold inflow-free solar chimneys can operate at higher efficiencies and achieve better performance.
Numerical and Experimental Investigation Results:
In this book, we will present comprehensive numerical and experimental investigation results to highlight the performance of cold inflow-free solar chimneys. We will use advanced computational fluid dynamics (CFD) techniques to simulate the air flow inside the chimney and analyze the temperature and pressure distribution. We will also conduct experimental studies to validate the numerical models and measure the performance of cold inflow-free solar chimneys in different environments.
Basic Design Parameters:
In addition to the design of cold inflow-free solar chimneys, this book also covers the important basic design parameters that affect the design of solar chimneys for different applications. These design parameters include the chimney height, diameter, and orientation, as well as the materials used in construction. By understanding these design parameters, architects and engineers can design solar chimneys that are tailored to specific applications and achieve optimal performance.
Applications of Solar Chimney:
Solar chimneys have a wide range of applications in different industries. In buildings, solar chimneys can be used for passive cooling and ventilation, reducing the need for air conditioning and improving indoor comfort. In industries, solar chimneys can be used for heat recovery and power generation, reducing energy consumption and improving process efficiency. In agricultural settings, solar chimneys can be used for crop drying and cooling, improving crop quality and yield.
Conclusion:
In conclusion, this book delves into the design of a novel solar chimney, featuring a lower height and a larger diameter, and explores its various applications. The introduction of larger diameter chimneys highlights the occurrence of cold inflow phenomena, which significantly diminish the performance of solar chimneys. However, the implementation of cold inflow-free operation in solar chimneys restores draft losses and enhances their performance. Comprehensive numerical and experimental investigation results will be presented to showcase the remarkable performance of cold inflow-free solar chimneys. Furthermore, this book encompasses the crucial basic design parameters that influence the design of solar chimneys for diverse applications, primarily focusing on solar chimney-assisted ventilation for passive cooling and power generation systems.
