EMAIL LIST If you are enrolled in the course you will be automatically subscribed to the course e-mail list using the address for your CU Plus account OVERVIEW The primary goal of AREN 2110 is for you to gain basic knowledge about fundamental concepts of energy and energy transformations with focus on engineering utilization of thermodynamic principles. Thermodynamics is used to analyze systems in virtually everybranch of civil and architectural engineering including applications in energy use and conservation in buildings and infrastructure systems, power generation, heating and cooling, fluid motion, behavior of chemical pollutants in soil, air and water, the hydrologic cycle, global climate change, and properties that determine the mechanical behavior of structural materials. In addition, energy has already emerged as one of the dominant themes in society over the next decades. Decisions about the sources, generation and distribution of energy will drive much of society’s actions and a fundamental understanding of the scientific and technical aspects of energy – thermodynamics – will be necessary for all citizens, especially engineers. My goal is to provide you with a variety of activities, in and outside of class, to enable you to learn fundamental theories and also engineering applications of thermodynamics. OBJECTIVES 1. Acquire the ability to analyze energy transformations in systems using basic concepts such as thermodynamic properties of materials, work, heat, internal energy, entropy, equilibrium, and relations derived from the First and Second Laws of Thermodynamics. 2. Conduct experiments to measure thermodynamic properties and to evaluate cyclic processes. 3. Carry out thermodynamic analysis of engineering devices and systems such as piston-cylinders, compressors, turbines, pumps, heat exchangers, heat engine cycles, and refrigeration cycles using energy, materials, and entropy balances. 4. Learn applications of thermodynamic concepts in Civil, Environmental & Architectural Engineering such as sustainable energy technologies, conservation, and maintaining the global environment. ACTIVITIES Information from lectures and the course text will be emphasized in weekly problem sets and assignments, and three exams (two midterms and a final). In-class problem-solving. Regular review sessions outside class. Homework will generally be assigned each week on Friday and will usually be due one week after the assignment. Homework assignments will be handed in individually unless a group project is explicitly assigned. Study group discussions of homework are often helpful PROVIDED that each student turns in assignments that are their individual effort and that it is his or her responsibility to learn the material. Instructors and the teaching assistant will have regular office hours as well as review sessions. You are strongly encouraged to come to office hours with questions on material and assignments. Also,comments and suggestions on ways to improve your own (and others’) understanding of thermodynamics will be greatly appreciated at any time in the semester.
