Applied Hydrodynamics

Module aims

This course aims to:

  • Provide an enhanced understanding of fluid flows with a strong emphasis on fluid loading.
  • Investigate both steady and unsteady flows appropriate to a wide range of hydrodynamic (water based) civil engineering applications. Examples are drawn from across the offshore, coastal, open-channel and marine renewable engineering sectors.
  • Introduce the fundamentals of the loading processes and the development of simplified models appropriate to design calculations.
  • Cultivate a high-level design capability involving the solution of practically important hydrodynamic problems.

Learning outcomes

On successfully completing this course unit, students will be able to: 

  • Gain a physical insight into a wide range of practically relevant fluid flows. 
  • Use approximate solutions and assess their applicability from a fundamental perspective. 
  • Understand the limitations inherent in most engineering solutions, appreciating when they can be confidently applied in engineering practice. 
  • Undertake design calculations in a wide range of fluid flows. 
  • Understand the benefits of varying types of marine renewables, design approaches and inherent approximations.
