Energy2D software can be downloaded here: http://energy.concord.org/energy2d/ After opening the application, choose File -> Open and select one of the .e2d files available for download here under additional files. Click the Run button to get started. The main download has a document that provides a detailed description of the adaptation of a freely available software program, Energy2D, for problems focused on the exploration and limitations of assumptions made in models commonly used in an undergraduate heat transfer course. The motivation for creating homework problems that use Energy2D is to explore the accuracy and limitations of the models used in heat transfer. The models are commonly utilized because they are easy to use and accurate even when not entirely valid, so these problems will provide students with a better understanding of their accuracy and of when they break down. Examples of models that are used here include 1D steady conduction with no generation, assuming a uniform base surface temperature or uniform convection coefficient for extended surfaces, using shape factors for 2D steady conduction, and the lumped capacitance method for transient conduction. Additional problems were in the process of being developed and will be continually developed during the Spring 2021 semester. The remainder of the document will be organized by problem in order of their coverage in MAE 3440 Heat Transfer at Utah State University. |
