Fluid mechanics has profound importance in Earth and planetary sciences because various phenomena on the Earth and planets are related to the dynamic motion of the fluids. This course is designed as an introductory course for fluid mechanics for Earth and planetary sciences: it begins with fundamental aspects of fluid mechanics and will deal with typical fluid motions in the field of Earth and planetary sciences.
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.
