Abstract

An experiment has been developed for the investigation of the sudden discharge of compressed gas from a pressure vessel through a chocked covering or converting-diverting nozzle. This experiment is used in required sensor-level course, ″Thermal Science laboratory″ in the mechanical engineering curriculum at the University of lllinois at Urbana Champaign (UIUC), the course has an enrollment of approximately 200 students per year. This discharge problem has many `Real world' applications, and hence is easily motivated for inclusion in a senior-level course. Although this experiment has excited in our curriculum for several years, the addition of computerized data acquisition system based on a Macintosh computer using graphical `Object Oriented Programming' software pressure transducers and thermocouples simplifies the collection of data, provides instant graphical representation of the data on the computer monitor, and also demonstrates to the students the power and utility of ordinary desktop computers in a laboratory environment. The experiment is relatively inexpensive to fabricate and yields excellent, repeatable data which agree well with the theory developed for the chocked discharge process.
