Fluid Mechanics Lesson 13A: Introduction to Boundary Layers

Fluid Mechanics Lesson Series - Lesson 13A: Introduction to Boundary Layers. This video was recorded on Halloween; watch for a special guest appearance. In this 15.5-minute video, Professor Cimbala explains the concept of a boundary layer, and describes the boundary layer coordinate system used to analyze boundary layers. He then derives the boundary layer equations for steady, two-dimensional, incompressible flow and explains the significance of pressure remaining approximately constant through the boundary layer. This video incorporates material from Section 10-6 of the Fluid Mechanics textbook by Cengel and Cimbala, Edition 4. An Excel file listing of all the videos in this series, along with the annotated notes generated during filming of the videos, can be found at https://www.me.psu.edu/cimbala/Cengel_Cimbala_book/Supplements/List_Fluid_Mechanics_Lesson_Videos_for_CC_Book.xlsx .
