Module overview
This module will develop the fundamentals of fluid mechanics in the context of naval architecture and ocean engineering including water waves and the fluid loading and motion of maritime structures and vessels in waves. The module continues from the more descriptive fluid mechanics material in part 1 and part 2, and develops the conceptual, mathematical, and computational techniques needed for the evaluation of added mass, unsteady boundary layers, ship roll and seakeeping.
