 SHE Level 3 SCQF Credit Points 20.00 ECTS Credit Points 10.00 Module Code M3H324727 Module Leader Martin MacDonald School School of Computing, Engineering and Built Environment Subject SCEBE - School Office Trimesters A (September start) B (January start)

### Summary of Content

The module will cover the fundamental principles of thermo-fluid mechanics (Thermodynamics & fluid mechanics) for a range of practical engineering problems. The theoretical limitations posed by the second law of thermodynamics are emphasized.

### Syllabus

The First Law of Thermodynamics: Introduction: cyclic systems, Closed systems, internal energy, displacement work, Open systems, flow work, enthalpy. Property Relationships. Phases of matter of a pure substance, tabulated property data for condensable fluids (eg steam), Perfect gas property relationships, equation of state for ideal gas, internal energy and constant volume specific heat enthalpy and constant pressure specific heat, ratio of specific heats. Thermodynamic Process Path Definition: Polytropic process, Special cases: constant volume (isochoric), constant pressure (isobaric), constant temperature (isothermal) process for an ideal gas. The Second Law of Thermodynamics: Reversibility, statement of the Second Law, perpetual motion of the second kind, Heat engine performance, reversible heat engines, thermodynamic temperature scale, temperature and heat engine performance. The Carnot cycle, Entropy relationship to heat transferred in reversible processes. Entropy property relationships, T-S, diagram and tables for real fluids, perfect gas relationships, the isentropic process for perfect gas, work done in a reversible steady flow process. The Carnot cycle, The Air-standard Cycles, Processes of making up the cycle, Cycle thermal efficiency, Compression/Expansion ratio and cycle efficiency. Introduction to fluid mechanics and applications: Scope of fluid mechanics; application areas, Energy - Bernoulli's equation (including link to 1st law of thermodynamics), Application of conservation laws to flow measurement. Solve problems involving Bernoulli's Equation. Define laminar and turbulent flows, determine and apply the effects of pipe-wall friction on fluid flow, determine and apply Reynolds number in fluid flow problems, relate pipe-wall friction factor to Reynolds number and wall roughness. Dimensional analysis, Geometric similarity, Dimensional homogeneity, Typical non-dimensional groups within fluid mechanics, Buckingham Pi theory.

### Learning Outcomes

On completion of this module students should be able to: 1. Apply the fundamental principles of thermodynamics and fluid mechanics to energy conversion systems.(AM1, AM6)2. Describe the basic concepts of real and perfect gases (AM1,AM6)3. Assess elementary thermodynamic cycle to describe the effects of the major operating parameters on performance of thermodynamic processes.(AM1, AM4)4. Demonstrate the performance of thermo-fluid systems through analytical methods including the use of empirical relations evolved from non-dimensional numbers (AM1, AM4/AM5)5. Demonstrate the principles of fluid mechanics and thermodynamic systems through laboratory experiments supported with data analysis and interpretations. (AM4)

### Teaching / Learning Strategy

The lectures will be used to convey the concepts of principles covered with suitable explanatory examples. The material covered during the classroom lectures will be reinforced and consolidated through tutorials and laboratory sessions. Private study will be used to reinforce materials delivered on relevant topics. Practical work in the laboratory will be used to encourage team work, enhance understanding and application of the engineering principles and develop skills in technical report writing.
