Integrating Thermodynamics and Fluid Mechanics Instruction: Practical Solutions to Issues of ConsistencyAbstractHistorically, the disciplines of fluid mechanics and thermodynamics have been taught as separatecourses using separately developed textbooks. Most undergraduate students form an early beliefthat these two aspects of thermal-fluid science and engineering are as far removed from eachother as cats are from dogs. It is not until the senior year or even into their graduate schoolexperience that the student begins to understand and appreciate the underlying physicalconservation laws upon which both of these disciplines are based. As a result of mechanicalengineering curriculum revision at the XXXXXXX at XXXXX, separate courses inthermodynamics and fluid mechanics were integrated into a two-course sequence, Thermal-FluidSystems I and II, in academic year 2005-2006.While succeeding in developing the two disciplines together under one overarching set ofphysical laws, there was still an issue with finding a suitable textbook. After four years ofinstruction using available text books from publishers, the mechanical engineering facultydeveloped a text tailored specifically to the integrated two-course sequence. The experience inwriting a text that integrates concepts in thermodynamics and fluid mechanics highlights theneed for consistency between the two disciplines.Issues identified include logical organization of topics, selection of appropriate variables,consistent use of sign convention throughout all topics, recognition of various forms of the samefundamental principle, and definition of performance parameters. This paper explores theseissues and how they were addressed for integrated instruction of thermodynamics and fluidmechanics. Feedback gleaned from student surveys and faculty comments with regard to theinitial implementation of the text were used to modify the text and examples. Performancefeedback and newly identified issues are presented.Bibliography1. Boettner, D., Norberg, S., Melnyk, R., Highley, J., Rounds, M., and Arnas, A.
