I modeled the transient flow of air through a nozzle. You learned how to generate a steady-state solution as a initial condition for transient case, how to set solution parameters for implicit time-stepping.
I also learnt how to manage the file saving and graphical postprocessing for depedent flows, using file autosaving to automatically save solution information as the transient calculation proceeds.
Finally, I learnt how to use ANSYS FLUENT's solution animation tool to create animations of transient data, and how to view the animations using the playback feature.
Given Problem :-
Flow through a simple nozzle is simulated as a 2D planar model. The nozzle has an inlet height of 0.2 m, and the nozzle contours have a sinusoidal shape that produces a 20% reduction in flow area. Due to symmetry, only half of nozzle is modeled.
