Fluids are everywhere around us; they are in every home, industry or ecosystem. Water and air are the basics of life, and how they are handled and controlled is key to many of our societal challenges, including climate change, flood and water management, food production, energy transition, healthcare and high-tech manufacturing. In this course you will learn about the basic physical mechanisms that govern the motion of and transport by fluids and see how these principles are applied in our daily lifes, nature, and industry.
