This paper contains a contrast and comparison between two approaches to introductory engineering courses. One approach is for each engineering department to offer its own distinct freshman engineering course independent of all other departments. The other approach is to offer an interdisciplinary freshman engineering course common for all engineering students regardless of department. In order to take advantage of the benefits of each approach a new freshman course has been developed at the University of Texas at Arlington (UTA). The developmental process from problem identification to final course description will be discussed. Also discussed will be the advantages of the newly developed course as compared to the other structures. Departmental Specific Freshman Courses This section discusses the advantages and disadvantages of each department within the College of Engineering (COE) having its own distinct freshman engineering course. One advantage of this approach is that each department sets the content of their course. This allows each department to teach the skills and tools that will be needed for students to be successful in the chosen discipline. The Computer Science and Engineering (CSE) Department, for example, could present a segment in contemporary issues in computer science, while the Civil and Environmental Engineering (CEE) Department would introduce CAD/CAE applications. Departments could also choose the structure of the course that would best fit the specific departmental objectives. For some departments lab time might be a necessary component while for other departments class lecture time might be a more appropriate format for the course. Again, departments could fit the course to their own objectives.

There are a variety of ways engineering ethics can be taught in the university. One common approach is to use case studies. Engineers like to think of themselves as practical people, and examining actual situations appeals to many engineers. In their popular book, Engineering Ethics: Concepts and Cases 1 , Harris, Pritchard, and Rabins use many real world case studies to illustrate the issues that are faced by engineers. Texas A & M University has created an extensive engineering ethics web page with many useful case studies 2 . In order to make the cases more interesting to the average engineer, a number of cases with significant numerical components have been created and posted on Texas A & M University’s Engineering Ethics web page 3 . Two of them are by the first author of this paper 4,5 . Another example of the case studies approach is in the first author’s paper at the 2002 Regional GSW ASEE meeting 6 . While case studies can be quite useful, and we have been involved in creating some of them, they may not be sufficient to give guidance in all situations. A second approach emphasizes the making of good decisions. Harris’ book 1 discusses various decision making methods. One way an engineer can make good decisions is to have a firm perspective on the world that helps her to evaluate each case that comes to her. This leads to the issue of using moral theories to help make ethical decisions. Martin and Schinzinger’s books 7,8 provide more information to the engineer about what moral theories are and how they can be used. Their first book 7 describes moral theories in more detail and we have used them to evaluate the legitimacy of the various engineering codes of conduct 9 . One problem with both the case studies approach and the good decision making approach is the question of what should be used as the basis upon which to decide. Many authors have used the engineering codes of conduct as their basis. However, as we have previously pointed out 9,10 , these codes are not perfect, and will not cover all the possible issues that the engineer might face. We

This paper reports on a novel flow visualization study in which the two-phase flow behavior of R-134a in a small-bore capillary tube is viewed from inside of the tube using a fiberscope. All previous capillary tube flow visualization studies, some dating back nearly fifty years, have used glass tubes through which two-phase flow behavior was observed and photographed from the outside. Because glass tubes have extremely smooth inner walls in comparison to the relative roughness of a drawn copper capillary tube, the two-phase flow behavior may be different. The proper characterization of the two-phase flow field downstream of the flash point is necessary for an accurate prediction of pressure drop and flow rate in the capillary tube. The fiberscope used was a 0.020 in. (0.51 mm) diameter glass fiber bundle roughly 39 in. (1 m) in length with at teflon coating. The fiberscope was inserted into the upstream end of the capillary tube through a specially designed fitting. The fiberscope lens at the end of the fiber bundle was positioned approximately 32 in. (80 cm) downstream of the capillary tube inlet. By carefully controlling the upstream pressure and temperature, the location of the onset of vaporization, or flash point, could be positioned near the fiberscope lens. In this way, the twophase flow detail could be viewed in the region of the flash point. The flow visualization results presented herein clearly indicate that once the vaporization is initiated the two-phase flow appears to be plug/slug-like, in contrast to developing bubbly flow behavior reported for the glass tubes in previous studies.
