# Introduction to Fluid Dynamics - 2023 entry

MODULE TITLE CREDIT VALUE Introduction to Fluid Dynamics 15 ENG2007 Dr Mohammad Akrami (Coordinator)
DURATION: TERM 1 2 3
DURATION: WEEKS 11
DESCRIPTION - summary of the module content

Almost all engineered objects are immersed either in air or water (or both), or make use of some working fluid in their operation. This is particularly true of machines for energy generation and conversion, such as engines, turbines, renewable energy devices such as wind turbines or wave- energy converters.

The ability to understand and predict the behaviour of such devices is therefore of key importance for engineers. In this module, you will learn about the fundamentals of fluid systems; pressure, flow and viscosity, and how they can be analysed experimentally and mathematically. Engineering applications covered include pumps and turbines, and internal flows in pipe networks.

AIMS - intentions of the module

By the end of this course, you will have the skills to analyse engineering systems involving internal and external flows, using experimental and mathematical techniques together with tables and charts of fluid dynamical and physical properties.
