Robust and fast methods for chemical or multiphase equilibrium calculation are routinely needed by chemical-process engineers working on sizing or simulation aspects. Yet, while industrial applications essentially require calculation tools capable of discriminating between stable and nonstable states and converging to nontrivial solutions,…

Previous work focused on use of computer graphics in teaching thermodynamic phase equilibria for classes I and II. Extends this work to include the considerably more non-ideal phase behavior shown by classes III, IV, and V. Student and instructor response has been overwhelmingly positive about the approach. (JN)

Describes an interactive graphics package which illustrates the phase behavior of binary mixtures. The package has been successfully used with graduate and undergraduate students in the chemical engineering curriculum at Cornell University. Features contributing to this success are noted. (JN)

Describes an interactive computer software package that uses graphics to teach staged operations (particularly the McCabe-Thiele method). Criteria used in developing the package and advantages for instructors and students are considered. (JN)

Computer programs that generate projections of thermodynamic phase surfaces through computer graphics were used to produce diagrams representing properties of water and steam and the pressure-volume-temperature behavior of most of the common equations of state. The program, program options emphasizing thermodynamic features of interest, and…

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Examines current uses and future possibilities of computer graphics in chemical engineering, discussing equipment needs, maintenance/manpower costs, and plan to implement computer graphics into existing programs. The plan involves matching fund equipment grants, grants for development of computer assisted instructional (CAI) software, chemical…

This paper describes the development of a software program which incorporates interactive graphics techniques into a teaching and research environment at the Department of Chemical Engineering, Technion, Israel, and the experience of transferring the software from mainframe to personal computer (PC) operating systems at the California Institute of…

Describes the design and development of a computer simulation and accompanying software to teach the scaleup of chemical processes to chemical engineering students at Penn State. Collaboration on the instructional development team is described, software modules are explained, and students' evaluations of the system are reported. (LRW)

Describes the use of a microcomputer program which was written to analyze batch reactor data by the integral method. Discusses how the program is structured and used by students in engineering kinetics. An example problem is included along with the computer's solution. (TW)
