Pre-requisite qualifications
Bachelor degree in Physical or Engineering SciencesThis module is not approved as an Elective
Objectives
On successful completion of the module the student will have a comprehensive understanding of lubrication theory, lubricants, greases and ElastoHydrodynamic Lubrication. The student will then be able to apply this to study real, industrial, engineering systems where lubrication is critical to the systems performance.Learning outcomes
On completion of this module students will have learned how to:
1. Apply lubrication theory to a range of relevant problems (including how complex lubricant rheology such as non-Newtonian, pressure dependent and temperature dependent lubricants perform). The analyses include the derivation and application of Reynolds equation and the sort bearing approximation;
2. Understand how different lubricants perform in real engineering environments (such as temperature dependence, degradation);
3. Understand the fundamental aspects of grease lubrication;
4. Apply Elasto-hydrodynamic Lubrication theory to analyse bearing performance and recall the standard bearing design rules.
Upon successful completion of this module the following UK-SPEC learning outcome descriptors are satisfied:
A comprehensive understanding of the relevant scientific principles of the specialisation (SM7M)
Ability both to apply appropriate engineering analysis methods for solving complex problems in engineering and to assess their limitations (EA6M)
Awareness of relevant regulatory requirements governing engineering activities in the context of the particular specialisation (EL12M)
Advanced level knowledge and understanding of a wide range of engineering materials and components (P12M)
Apply their skills in problem solving, communication, information retrieval, working with others, and the effective use of general IT facilities (G1)
Skills outcomes
Mathematical analysis, programming (matlab)
