Ogee Spillway CFD Simulation

Explore dynamic hydraulic engineering with this ANSYS Fluent tutorial on transient Ogee spillway simulation using the Volume of Fluid (VOF) method. This module introduces you to the complexities of time-dependent free-surface flow analysis in a critical hydraulic structure.

Key aspects covered: • Applying the VOF model to simulate the time-varying behavior of water flow over an Ogee spillway • Utilizing the pre-configured geometry of an Ogee spillway in ANSYS Fluent • Implementing time-dependent boundary conditions for water inlet and air-water interface • Configuring VOF parameters and time-stepping for accurate interface tracking over time • Analyzing evolving water flow patterns, velocity profiles, and pressure distributions • Investigating the temporal effects of flow rate and spillway design on hydraulic performance • Interpreting transient simulation results to understand dynamic spillway behavior

Through guided simulations, you’ll gain hands-on experience in applying the VOF method to track the dynamic, time-varying interface between water and air. This tutorial provides essential skills for simulating transient free-surface flows in hydraulic structures.

By the end of this module, you’ll understand how to use ANSYS Fluent’s VOF model to simulate and analyze time-dependent free-surface flows in spillways. This knowledge is crucial for civil and hydraulic engineers working on dam design, flood control, and other applications involving dynamic open channel hydraulics.
