We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Viscous Fluid Flow

This learning track covers a comprehensive understanding of fluid dynamics, starting with the advanced aspects of viscous fluid flow. It delves into the Navier Stokes equations, exact solutions for steady one-dimensional rectilinear flows, steady axis symmetric flows, and more. The track further explores the analytical solution of Navier Stokes equations for simplified problems and simple geometry. It also provides a detailed understanding of fluid dynamics in cylindrical coordinates, Stokes problems, and fluid dynamics in various duct shapes. The learning track then transitions to the comprehensive understanding of lubrication theory and its applications in various mechanical systems. It also covers the comprehensive understanding of boundary layer flows, a crucial aspect of fluid dynamics. The track also explains the stability theory and analysis in fluid dynamics used to understand the transition from laminar to turbulent flow and the significance of the Reynolds number. Lastly, the track concludes with a comprehensive understanding of turbulent flows, their applications in engineering and nature, and the mathematical equations used to predict their behavior.
