Cylinder boundary

WebUnlike an ideal inviscid fluid, a viscous flow past a cylinder, no matter how small the viscosity, will acquire a thin boundary layer adjacent to the surface of the cylinder. Boundary layer separation will occur, and a trailing wake will exist in the flow behind the cylinder. The pressure at each point on the wake side of the cylinder will be ... WebStudents will learn how to solve for the steady and unsteady two-dimensional flow around an infinite cylinder. Before students take this course, they should have some basic knowledge of single-variable calculus, vector calculus, differential equations, matrix algebra and numerical methods. Students should also be able to program in Matlab.
