Work in progress - a Web-based virtual supersonic nozzle module as a visualization and active learning tool for the undergraduate thermodynamics course

A Web-based visualization tool has been developed and used for teaching undergraduate students about flow and thermodynamic property variations in isentropic (shock-free) and non-isentropic (normal shock embedded) one-dimensional compressible flows in nozzles. The Web-based module simulates these flow regimes by numerically solving conservation laws for mass, momentum and energy, and enables real time visualization of results using an animation program. The module through its interactivity feature permits students to change operating pressure conditions to visualize flow property variations inside a supersonic nozzle by clicking and dragging action of a computer mouse. The module through a variety of visual images of physical phenomenon also provides student the engineering context of underlying engineering principles and governing equations
