Module Code - Title: ME4516 - THERMODYNAMICS 2 Year Last Offered: 2017/8 Hours Per Week Grading Type: N Prerequisite Modules: ME4523 Rationale and Purpose of the Module: To provide an understanding of the mode of operation for actual heat pump and refrigeration systems and to analyse their performance characteristics. To provide an understanding of the mode of operation of Rankine, superheat, reheat and regenerative steam power cycles and to analyse their performance characteristics. To analyse the power output characteristics of pure impulse turbines and impulsereaction axial flow turbines. To relate the performance and characteristics of the latter to steam enthalpy change in multi-stage operation. To analyse the power input requirements, volumetric efficiency and heat loss characteristics for single stage and multi-stage compressors. To provide an understanding of the mode of operation for actual 2-stroke and 4- stroke spark ignition and compression ignition engines and to analyse their performance characteristics with reference to mean effective pressure, indicated power, brake power, specific fuel consumption, volumetric efficiency, thermal Syllabus: Axial and Radial Flow Turbines and Compressors. Reciprocating expanders and compressors. Vapour Power Cycles. Gas Turbine Cycles. Performance of Internal Combustion Engines. Learning Outcomes: Lecture Lab Tutorial Other Private Credits 3 0.83 0.83 0 4 6 Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis) Using appropriate refrigerant charts and tables of properties, analyse refrigeration and heat pump cycles to estimate refrigeration effect, compressor work, heat rejected and coefficient of performance for a range of systems including 2-stage industrial refrigeration systems. Using both tables of thermodynamic properties the entropy-enthalpy chart for steam analyse the efficiencies of Rankine, superheat, reheat and regenerative cycles, and specify salient state points and performance parameters. Recognise the mode of operation of real reciprocating Internal Combustion engines as opposed to Otto, diesel and dual air standard cycles, and determine performance characteristics for reciprocating internal combustion engines. Given preferred delivery conditions specify power requirements and cylinder dimensions and efficiencies for single- and multi- stage reciprocating compressors; and derive intermediate pressures and energy balance for multi-stage compressors. Describe the fundamental basis for mechanical power generation in impulse and impulse-reaction turbines, and given input and output velocity and geometric criteria generate velocity triangles and use these and the entropy-enthalpy chart for steam to determine power output, efficiencies and reheat factor for multi-stage impulsereaction turbines. Affective (Attitudes and Values) Improve understanding of thermodynamics as it applies to practical engineering, especially in the power industry. Psychomotor (Physical Skills) Experimental evaluation of coefficients of performance for a combined heat pump and refrigerant. Performance evaluation of a Rankine cycle steam plant.
