Laminar Free Shear Flows

This course covers the comprehensive understanding of laminar free shear flows. It begins with the exploration of two-dimensional laminar jets, explaining the governing equations and assumptions made for large Reynolds number flows. For instance, learners will understand how to calculate the velocity distribution of a jet where the velocity becomes almost 1% of the center line velocity. The course then moves to the study of flow near a wake behind a flat plate of finite length, explaining how velocities become self-similar about three lengths downstream. Lastly, the course delves into the free shear layer between two streams with different velocities, introducing the concept of similarity variables and the use of numerical methods like finite difference method, finite volume method or finite element method to solve the boundary layer equation.
