Web-Based Thermodynamics Tables Wizard

C. C. Ngo and F. C. Lai School of Aerospace and Mechanical Engineering University of Oklahoma Norman, Oklahoma 73019

Abstract

In the study of Thermodynamics, looking up thermodynamics properties from tables has been an essential skill that students need to acquire. Since more higher education institutions are now offering online courses or Web-teaching, the challenge that one faces is how to make use of the multimedia technology to teach students to use thermodynamics tables and facilitate the properties look-up process via the Web.

This paper presents the Web-based Thermodynamics Tables Wizard and how it can be used to accommodate the needs of students at different levels in looking up thermodynamics properties. For students in their early stage of study, interactive workshops are provided for them to study the basic relations among various thermodynamics properties when using the tables. In addition, an interpolation tool along with interact ive thermodynamics tables has been designed to minimize the computational effort. Another feature of this wizard, which is especially designed for more advanced students, is its built-in thermodynamics functions which allow students to obtain thermodynamics properties without the need of tables. This Thermodynamics Tables Wizard can be used as a stand-alone studying aid or an add-on component for any online Thermodynamics course. The implementation of this Web-based module can greatly enhance the learning experience of students when they study Thermodynamics.

I. Introduction

In the study of thermal sciences, acquiring thermodynamics properties has been an essential part of problem solving. Thermodynamics properties are most often presented in a t abulated form and are included in a thermodynamics textbook 1-3. They are also available in several commercial packages which sometimes are distributed through the sale of a textbook. For example, through the distribution of thermodynamics textbook by Moran and Shapiro 1 is a software package called Interactive Thermodynamics (IT) 4 developed by IntelliPro, Inc. Similarly, the textbook by Sonntag et al. 2 comes with a software package called Computer-Aided Thermodynamics Tables
