##### Semesters
 Semester 2 Credit Value: 20 ECTS Credits: 10.0

#### Aims

1. Fluid Mechanics:
This course aims to generalise fluid mechanics so that at a later stage, the knowledge gained can easily be used in numerical simulations, such that the students understand the meaning and implications of exact/approximate solutions in the description of fluids, flow geometry and flow kinematics. Governing fluid flow equations, including the equations of state, are obtained in 3D form in tensor notation and applied to the flow of Newtonian and non-Newtonian fluid flows in simple geometries. More complex fluid systems such as compressible and multi-phase fluids are also examined and related to the process industries.

2. Heat Transfer:
i. To extend the knowledge of the principles of heat transfer and to provide a fundamental knowledge of design criteria for typical forms of heat exchangers used in the process industries.
ii. To enable the students to analyse heat transfer in systems where there is change of phase.
iii. To allow the students to analyse systems where radiative heat transfer is significant/dominant.
iv. To ensure that students can design and choose appropriate equipment in their design projects.

#### Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

##### Assessment Rationale And Relationship

The unseen examination is used to assess the understanding of the basic principles of fluid mechanics and heat transfer as well as the ability to solve fluid flow problems starting from the general 3-dimensional forms of momentum equations or equations of state.

The design assignment assesses the studentsâ€™ ability to implement in detail the heat transfer and fluids knowledge gained in the course.
