Course overview and goals

Fluid mechanics is of paramount importance in Earth and planetary sciences, as many phenomena on Earth and other planets are associated with the dynamic motion of fluids. This course serves as an introduction to fluid mechanics within the context of Earth and planetary sciences. It starts with the fundamental principles of fluid mechanics and progresses to cover typical fluid motions observed in the field of Earth and planetary sciences.

Course description and aims

By completing this course, students will able to
(1) Understand the basic terms and equations of the fluid mechanics,
(2) Understand the basic aspects of the flow of inviscid, incompressible fluid,
(3) Understand the basic aspects of the flow of viscous fluid,
(4) Understand the basic aspects of the fluid mechanical stability.

Keywords

inviscid and incompressible fluids, viscous fluids, geophysical fluid dynamics
