Modules

MEC2003 : Applications of Thermofluid Dynamics

Semesters
Semester 1 Credit Value: 10
Semester 2 Credit Value: 10
ECTS Credits: 10.0

Aims

The aim is to provide a broadly-based extension of core knowledge and skills in this field of engineering science, with applications of more advanced thermofluid dynamics for students who have studied this topic at university level for at least one year previously, covering thermodynamics, fluid mechanics and turbomachines.

Outline Of Syllabus

Thermodynamics: Carnot cycle, second law of thermodynamics, Kelvin-Planck and Clausius statements, origin of irreversibilities, entropy, TdS relationships, properties of liquids and gases, process and cycle representation on T-s and h-s charts; turbines, compressors and isentropic efficiency; simple steam and gas turbine cycles (Rankine and Brayton), refrigeration cycles, combined cycles.

Heat Transfer: Conduction, Radiation and Convection, introduction to heat exchanges.

Mechanics of Fluids: Control volume linear momentum equation, momentum function and applications (reaction, propulsion etc.). Dimensional analysis and similarity, scale modelling; Laminar and turbulent pipe flow, Reynolds number and transition; Pipe flow resistance, friction factor and Darcy-Weisbach equation, friction factors for laminar and turbulent pipe flows (Moody diagram), local losses; pipe systems, losses in series, energy line and hydraulic gradient.

Fluid Machinery: Turbomachinery: principles of energy exchange, machine losses and characteristics; interaction with external system and operating point; non-dimensional groups. Cavitation.

Teaching Rationale And Relationship

- Lectures convey the underlying engineering sciences and the approaches required to apply these to the discipline-specific problems identified.
- Tutorials support the students' self-study in reading around the lecture material and learning to solve the practical engineering problems posed by the Tutorial Questions.
- Use of software in the projects enables students to investigate more complex (and thus realistic) problems than would be practical by hand calculation.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The end of year examination provides an appropriate way to assess both theoretical understanding and practical problem solving skills under time-constraint as required in industry.
The projects use software to allow more realistic and complex problems to be analysed.

For the purposes of professional body accreditation, in order to obtain a passing mark overall for this module (40%) at the first attempt the minimum acceptable mark for each of the assessment items specified below shall be 30%, with the maximum possible module overall mark where this is not the case being restricted to 35% (Undergraduate Progress Regulations):

(1) 45% Exam Sem 1
