Transient flow analysis in OpenFOFOM involves similatring fluid flow thatt oves over time. Ini adalah usu for studying unstatile exphe as turbulense, pulsations, or transient events.

Settingg Up the Simulation

Analize the trancient dating using visualization tools as ParaView. Review velociy fields, pressure distribution, and turbulence ovee time. This helps is in understang the flow obhadoir and identifying porope.
