Fluid-Solid Interaction: Fundamentals and Predictive Modeling

Fluid-solid interactions shape the physical world, governing how wind affects bridge structures, how blood flows through arteries, and how aircraft wings vibrate. Understanding these coupled forces is essential for designing safe, efficient, and resilient engineering systems. This written course guides you through the core physics and mathematical formulations behind these complex interactions. You will transition from understanding basic fluid and structural mechanics to predicting coupled behaviors and applying modern modeling strategies to prevent structural failure. What you'll learn: - Understand the foundational mechanics of fluid flow and structural dynamics and how they couple. - Identify and analyze key phenomena such as added mass, vortex-induced vibrations, flutter, and galloping. - Learn the fundamental equations governing sloshing and wave-structure interactions. - Explore modern computational coupling strategies, including partitioned and monolithic algorithms. - Evaluate engineering designs to mitigate destructive fluid-induced oscillations and instability. The course begins with foundational terminology and the basic physics of fluids and solids before moving into coupled governing equations. You will then explore specific physical phenomena, analyze real-world case studies, and review modern analytical and numerical modeling workflows through clear explanations and practical written exercises. Designed for engineering students, researchers, and professional designers new to fluid-solid mechanics, this course starts with foundational concepts and requires only a basic background in physics and calculus.
