This core module is designed to extend your knowledge of the analytical techniques of fracture mechanics, stress analysis and thermofluid to analyse and design engineering structures and systems.
This module builds on the knowledge gained in the second year Thermofluids & Mechanical Systems 2 module to extend your knowledge and skills in structural analysis based on fracture mechanics and fatigue. Simulation will be used to give a practical introduction to the finite element analysis (FEA) method for structural analysis. Thermofluids mechanics aspects involving conversion and transfer of energy such as turbomachines (pumps, turbines...) and heat exchangers will be discussed. The module also provides a further understanding of numerical methods employed in fluid flow and heat transfer analysis using computational fluid dynamics (CFD).
The module is primarily delivered through lectures supported by tutorials. Course materials are available via Canvas where appropriate.
On successful completion of the module, students will be able to:
The module is delivered through a variety of lectures, tutorials, computing workshops and presentation of a researched topic. Lecture material, tutorials and support material will be made available on Canvas. Use of LRC electronic resources such as iCAT and ebooks and resources available on internet are introduced and students are encouraged to use them. Lectures and tutorials are designed to introduce the students to the concepts necessary to understand the engineering problems associated with advanced thremofulids and structural analysis. Students will be expected to research contemporary issues around structural integrity including fracture and fatigue, failure analysis and current developments in thermofluids. The lectures and tutorial sessions will provide an opportunity to develop the students' deeper understanding of the application of theoretical concepts into real world engineering problems. Opportunities to provide detailed and overview feedback and feedforward will be available during the tutorial and practical sessions.

The module will be assessed as 50% coursework and 50% end of module unseen written examination.
The computing workshops and tutorial classes will provide formative assessment opportunities in the early stages of the modules, enabling feedback and feed forward to the summative events. The evaluation of a students' progress throughout the module will be assessed by two written coursework. One coursework includes failure analysis of a structure, hand calculation and using FEA commercial software to solve a structural problem and CFD analysis to solve a flow problem with commercial software. This coursework carries 30% of the total marks. The second coursework will focus on the application of thermofluids in rotodynamic machines and heat transfer. Students are expected to apply thermofluids theories to solve a range of the flow problems with a view to enabling the students to develop their critical analysis skills. This coursework carries 20% of the total marks.
