Fundamentals of Unsteady Turbulent Flows with Python Coding is designed as a text for advanced turbulence students who need to build on their elementary knowledge to develop a deeper understanding of turbulence applications in the real-world, including unsteady turbulent flows, buoyancy-driven atmospheric plumes, and oceanic density currents. After an introductory chapter that connects key mathematical equations with the physical concepts of turbulence, subsequent chapters explain how buoyant turbulent flows apply to a variety of natural systems such as unsteady turbulent flows, atmospheric plumes, and oceanic density currents. Concepts of rough walls, buoyancy effects, and statistically non-stationary flows are also covered. Fundamentals of Unsteady Turbulent Flows with Python Coding serves as a single-source toolkit that provides turbulence theory, data drawn from real-world examples, plus access to Python code modules that readers can use to practice interpreting the data. End of chapter problems help to further reinforce the concepts covered.
