A diverging nozzle is a device used to accelerate fluid flow, typically in applications involving gases or liquids. It features a wider exit diameter compared to its entrance, allowing the fluid to expand and increase in velocity as it passes through. This design is commonly found in jet engines and rocket propulsion systems, where efficient thrust generation is crucial. In a diverging nozzle, the pressure of the fluid decreases as it expands, converting pressure energy into kinetic energy. This principle is essential in various engineering fields, including aerodynamics and thermodynamics, where understanding fluid behavior is vital for optimizing performance and efficiency.
