Advancements in computer and mobile technologies have driven transformations of classroom activities in engineering education. This evolution provides instructors more opportunities to introduce computational tools that can be effectively used and promoted in engineering education to advance students’ learning process when the tools are appropriately utilized in the classroom activities. This paper presents a methodology to improve student learning of energy systems through a class assignment implementing a self-developed computational tool using Microsoft Excel and utilizing the tool to enhance their learning experience. The proposed method, a student-centered learning approach, was applied in a technical elective course called “Power Generation Systems” within a mechanical engineering curriculum. In the course, students were guided to develop a computational tool by themselves based on their learning of the fundamental principles and governing equations of a thermodynamics cycle. The self-developed computational tool allows the students to focus on more design-oriented problems, instead of the calculation process. Using the self-developed tool, students can have an enhanced understanding of the energy system performance in varying design and operational conditions and can perform the parametric analysis and visualization of essential parameters. Feedback from the students and class instructors proves that the self-development and use of the tool can significantly improve the students’ learning experience in the implemented course, make the course more dynamic, and motivate the students to learn the material more iteratively. In addition, students feel confident using computational tools to perform analysis, and are willing to develop more tools for other energy-related engineering applications.

“…Previous work 5,6 by the first author at automated property lookup involved use of the Thermal Fluids Toolbox produced by Spreadsheet World, Inc. when calculating properties for water vapor. Unfortunately, this Excel™ "add-in" is not employed in the current application because it could not provide property values for a wide variety of temperatures.…”

A mutli-faceted approach (lecture, spreadsheet and laboratory) used to teach introductory psychrometric concepts and processes is reviewed. During introductory lectures, basic thermodynamic principles are employed in the presentation of elementary psychrometric processes; various process lines are shown not only on traditional psychrometric charts, but also on temperaturevolume diagrams, with which the students are already familiar. During their first exposure to psychrometry, most students usually find the layout and interpretation of the psychrometric chart particularly difficult to comprehend; in the current approach, an interactive psychrometric chart (written in Excel™ using Visual Basic for Applications) allows students to use sliding bars to visualize in real time how lines of constant relative humidity, specific volume, and wet bulb temperature vary; the effect of varying barometric pressure may also be viewed by using another sliding bar. Students are then required to construct their own psychrometric charts in a parametric fashion, producing lines of constant relative humidity, specific volume, and wet bulb temperature; these charts are produced for the prevailing barometric pressure, rather than for standard atmospheric pressure.The instruction is supplemented with a simple laboratory, wherein wet and dry bulb temperatures are measured inside the classroom and outside, and which are, in turn, used to calculate relative humidity, specific humidity, and other parameters associated with the building air conditioning process. An integral part of this laboratory is that the psychrometric chart previously produced by each student in Excel™ is employed in the analysis-since it was constructed for the barometric pressure which was recorded during the experiment, students may use it in their data reduction, rather than the chart provided in their text (for standard atmospheric pressure). This synergistic approach has been found to enhance student understanding of the basic psychrometric and HVAC processes.

“…McDaniel 7 has developed a Thermal Fluid Toolbox which allows properties to be obtained in individual cells. This allows applications such as a combined cycle power plant 8 and many other applications with iterative design solutions 9 . McDaniel recently prepared a spreadsheet for the Computational Aero course at the USAF Academy that solves the one dimensional heat equation using both explicit and implicit methods.…”

A Spreadsheet Approach To Teaching Numerical Methods For Steady And Unsteady Heat Transfer

A unified method for teaching steady (using Gauss-Seidel) and unsteady (using Explicit) numerical methods for conduction heat transfer using a spreadsheet (Excel TM ) is described. This method makes use of the similarity between nodes in numerical heat transfer and cells in a spreadsheet. Extensive use is made of the electrical analogy for heat transfer in the difference equations. Students program in the difference equations and the boundary conditions in a template provided to them. Students prepare their own macros for the iteration schemes. The versatility of the spreadsheet approach allows spatially and temporally dependent boundary conditions which in turn permits almost immediate applications to engineering design including optimization. Steady heat transfer applications have included fins for electronic and engine cooling. Unsteady heat transfer applications have included the design of automobile and aircraft disk brakes. The advantage of this approach is that students prepare their own numerical model, which enhances understanding of the numerical methods and boundary conditions, explore convergence and stability criteria, and move quickly into thermal design studies using the numerical tool that they have developed.
