Lectures: Monday & Wednesday 13:00-14:15 in ENG-B16
Office Hour: Wednesday 14:45-15:45 or by appointment

TA: TBA

Requirements: Mech 301 or equivalent and strong background in differential calculus

Course Objectives:
The course is designed to teach senior and first year graduate mechanical engineering students the fundamentals of the classical fluid mechanics at an advanced level that is beyond the scope of the first fluid mechanics course. An introduction to the Cartesian tensors and derivation of flow equations in various forms. Solutions to the flow equations using scaling and approximations. Creeping flows, boundary layer theory, unidirectional flows, lubrication theory with applications in engineering and biological systems, and an introduction to turbulent flows and turbulence modeling. An introduction to modern computational tools and hands-on experience using a CFD package such as OpenFOAM.

Learning Outcomes
Upon successful completion of this course, a student will:

- be able to use Cartesian tensors to manipulate flow equations;

- understand the derivation and physical interpretation of the flow equations;

- understand and effectively use the scaling and approximations to obtain analytical solutions;

- understand the boundary layer theory, derivation and solution of the boundary layer equations;

- understand the lubrication theory, its limitations and applications;

- understand the concept of flow instability and turbulent flows;

- be able to use modern computational tools and interpret the results.
