| Description: | Interactive paper in: Advances in Engineering Education - Summer 2008 - Volume 1 - Issue 2. It has 3 videos that demonstrate the courseware: # Video 1: Figure 5. Different boiling regimes observed during the heat transfer experiment: (a) film boiling; (b) vigorous boiling after the vapor film starts to break down. # Video 2: Figure 7. (a) Front panel of the VI for the boiling experiment. (b) Remotely controlled LabVIEW front panel displaying real-time temperature data. Picture shows increasing temperatures as the ball is being heated in the furnace. Subsequent drop in temperatures due to quenching is shown in the video. # Video 3: Figure 10. A view of the webcast of the heat transfer lab as seen in a web browser at the remote site. Remote user can zoom, tilt and pan using the scroll bars on the bottom and right side of the window. Abstract: "Internet extends the reach of existing laboratory and training infrastructure to beyond the walls of such facilities. Though nothing can replace the hands-on experience in a laboratory; a carefully developed web-based digital lab may be the next best thing. In some cases, there may be benefits associated with a "distance laboratory" that are usually not available in a conventional lab. Due to radiation environment and very high cost of some labs - for example, nuclear research reactors - there exists a need to develop web-based systems that can access the experiments being conducted in a radiation measurement lab or the reactor and make it available in a virtual laboratory. These systems should be inexpensive, easily installable, allow interactive audio/video communication as well as remote access (or sharing) of data in real-time. We here report the development of a real-time, distance lab module that is being implemented in the Department of Nuclear, Plasma and Radiological Engineering at the University of Illinois. This internet-based system allows remote personnel to watch the experiments and personnel performing the experiments, acquire data, and interact (audio and video) with on-site personnel. Data are broadcasted in real time in text as well as graphical format—the same format used to display the data on site. Moreover, use of LabVIEW’s remote front panel feature allows communications between the local lab and remote client so that remote client, if permitted, can obtain part or full control of the experiments." |

Conclusions: "Using off the shelf technology, a boiling heat transfer e-Lab has been developed that can be a prototype for other similar experiments. The e-Lab successfully achieves the goals set out for such an exercise. It provides a rather realistic experience of the experiment to the student at the remote site. Although current emphasis has been on observation, data retrieval, and analysis of particular experimental sequences that illustrate or reinforce some basic physics or engineering concepts, future developments may also allow some limited control actions from the remote sites. With LabVIEW, internet and computers readily available in most laboratories, web-casting of these labs over the internet to sites around the world can be achieved with a modest cost. This prototype e-Lab will facilitate reaching a broader audience and enhance distance education programs. More importantly, it is hoped that the details provided in this paper will help in the development of other similar e-Labs." |
