• Explain the principles and working of experimental methods
• Collect data using different experimental methods
• Analyse data obtained via experiments using various statistical tools

Transferable and Generic Skills

Having successfully completed this module you will be able to:

• Demonstrate study and time management skills
• Design and develop experimental setups
• Study and learn independently including engaging with technical literature

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• Exposure to different measurement techniques, their viability and limitations in examining fluid flows
• Introduce tools for analysis of fluid flows
• Introduce aspects of experiment design and associated uncertainties.
• Experiment-conception and design to address problems in fluid mechanics
• Different statistical analysis tools as well as data manipulation methods and computational analyses
• Introduce major types of aerodynamic test facilities
• State-of-the-art measurement technology and its applicability and limitations

Full CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• Use practical laboratory skills to investigate complex experimental aerodynamics problems, as assessed via quizzes and laboratory reports related to laboratory exercises.
• In a laboratory report, select and critically evaluate technical literature and other sources of information on experimental flow measurement techniques and their applications to solve complex experimental aerodynamics problems.
• Through a report based on laboratory experiments and quizzes based on illustrative problems, apply a comprehensive knowledge of mathematics, statistics, scientific and engineering principles of state-of-the-art experimental flow measurement techniques and associated analysis to the solution of experimental aerodynamics problems.
• Through quizzes and in preparation for laboratory exercises, select and apply appropriate equipment, engineering technologies and processes to experimental aerodynamics measurement problems, recognising the limitations of the chosen methods.
• Through a laboratory report, formulate and analyse complex aerodynamics problems to reach substantiated conclusions. This will involve evaluating the available data using first principles of mathematics, statistics, natural science and engineering principles underpinning experimental flow measurement techniques. Using recognised standards to quantify measurement uncertainty, engineering judgement will be used to work with information which is uncertain or incomplete and to discuss the limitations of the techniques employed.

Formative

This is how we’ll give you feedback as you are learning. It is not a formal test or exam.

Coursework & Labs

• Assessment Type: Formative
• Feedback: Coursework marked and returned to students with individual comments. This will use the same style of marking scheme that the final coursework will use so they can build on this for their final report. General feedback will also be provided in the lecture.
• Final Assessment: No
• Group Work: No

Summative

This is how we’ll formally assess what you have learned in this module.
