Course Objectives

Understanding

Enhanced understanding of fluid mechanics, including the equations of motion in differential form, and turbulence.

Understand the basic concepts in computational fluid dynamics (CFD).

Understand the basic elements in the use of commercial CFD software.

Capabilities

For a given problem, be able to determine the appropriate differential equations of motion, initial conditions, and boundary conditions.

For a given problem, be able to determine whether the flow is laminar or turbulent, and whether a turbulence model is required in its solution.

For an application involving fluid mechanics, be able to utilize a commercial CFD software program in the problem solution.
