Description

The objective of this module is to introduce students to the theory and practice of hydraulic and turbomachine design. The theory is used to explain design methods and principles and is applied to solve a range of practical and simplified problems. The practical part of the course involves a design challenge. The students will work in teams to develop and assess a micro-wind turbine, where the design will be based off a numerical optimization using a Blade Element Momentum technique. The performance of the design will then be assessed by means of experiments in a wind tunnel.

Learning Outcomes

1. Interpret the theoretical foundations of fluid mechanics in turbomachine design
2. Report on the aerodynamic characteristics of a 2D airfoil profile
3. Carry out a theoretical assessment of turbomachine performance from idealised flow velocity diagrams
4. Predict the performance of an airfoil or hydrofoil using a potential flow simulation tool
5. Carry out aerodynamic design of a wind turbine using a BEM solution
6. Understand the selection criteria for pumps including scaling laws
7. Implement a numerical optimisation solution for wind turbine design
8. Work in teams to model and design a pumping or mixing solution
9. Design a turbomachine from specifications defined to meet an industry need
10. Integrate CFD and CAD tools to a practical and industry relevant engineering design challenge
11. Analyse a hydraulic network

Course Work Breakdown
Project	Students will work in teams to design a micro-scale wind turbine for a specified range of operating conditions. The teams will follow a numerical optimization driven design process. They will integrate a BEM/DMST model and virtual design tools and will test the suitability and performance of their design, which must be suitable for 3D printing. This exercise will involve designing a micro wind turbine and measuring the power curve in a wind tunnel. The assessment may include among other a technical report, oral/poster presentation, multimedia and/or Loop Quizzes.	50%	n/a

Reassessment Requirement Type
Resit arrangements are explained by the following categories: Resit category 1: A resit is available for both* components of the module. Resit category 2: No resit is available for a 100% continuous assessment module. Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
This module is category 1
