MECE-110
3 Credits
A basic course introducing the classical theory of thermodynamics. Applications of the first law of thermodynamics are used to introduce the student to thermodynamic processes for closed and open systems. The Clausius and Kelvin-Planck statements of the second law are then correlated with the concept of entropy and enthalpy to investigate both real and reversible processes and the thermodynamic properties of pure substances. These techniques are then used to evaluate thermodynamic cycles for a variety of applications in power generation and refrigeration. Students are then introduced to techniques to improve thermal efficiency of these cycles such as reheat, regeneration, and co-generation.
MECE-352
3 Credits
Advanced design and analysis of gas and vapor power cycles, including co-generation and combined cycles, as well as vapor compression and air-conditioning cycles using concepts of exergy based on the 2nd Law of Thermodynamics and the field of thermo-economics. Emphasis is also placed on determining entropy generation and irreversibility within fossil fuel combustion processes using chemical energy.
MECE-401
3 Credits
This applied course introduces students to the analysis and design of heating, air conditioning and refrigeration systems. Topics include human comfort, ventilation, heating and cooling building loads, energy use modeling, psychrometric properties and processes, mechanical vapor compression and absorption refrigeration cycles, air conditioning systems and equipment. Students will do a team design project.
MECE-421
3 Credits
This course introduces the operation and design of internal combustion engines. Pressure versus volume charts will be used to compare performance parameters. Other topics include engine types and cycles, fuel injection systems, and emission control systems. New technologies to reduce emissions and increase fuel efficiency will be discussed.
