This online course will help you to develop a sound understanding in the theory and application of thermodynamics, especially as related to heat engines, process and environment heating/cooling.
The course will cover the following
- Thermodynamics
- Gas cycles, power, efficiency, work
- Engines, operation principles, pressure charging, trials, indicated and brake power
- Steam and gas turbines, principles, application of cycles, constructional features, heat exchanger effectiveness
- Energy conservation and environmental effects
- Conservation in plant, waste heat recovery, overall efficiencies, co-generation plants
- Process heat, heat sources and energy transport systems, applications to process plants
- Steam generating plant and cycles, boiler types, feed systems and components, feed water contamination and treatment, boiler efficiencies
- HVAC systems, humidity, heating cooling loads, Load line, recycle air, fresh air, plant layout
- Fuels and combustion calculations, chemical equations, air/fuel ratios, analysis of exhaust gases, solid, liquid and gaseous fuels, preparation of fuels for use, fuel storage and application
- Air compressors, Inter cooling, Volumetric efficiency
On successful completion of this course, you should be able to
- Demonstrate an understanding of the laws of thermodynamics
- Analyse common Internal combustion engine cycles and explain their operation and their effects on the environment
- Demonstrate an understanding of process heating/cooling systems
- Explain nozzle terminology, calculate velocities and pressures
- Outline HVAC system operation and equipment and determine heating, cooling and dehumidifying loads
- Determine air/fuel ratios and exhaust analysis for common fuels and describe handling requirements
Assessment
- Internal assessment 50%
- Examination 50%
