Spillway (2-D & Transient) CFD Simulation, Two-Phase Flow, ANSYS Fluent Training

Project description

If any obstacle is placed on the path of the fluid flow, it causes the fluid level to rise behind it and increase its velocity, which eventually leads to fluid overflowing over the obstacle. These obstacles are regarded as spillways. spillways have different uses depending on their shape and are mostly used in civil engineering. In this project, the two-phase flow of water and air flowing over an ogee spillway is simulated by ANSYS Fluent software. The water will enter the computational domain with a mass flow rate of 0.05 kg/s and it flows over the spillway. The standard k-epsilon model is exploited to solve fluid flow equations and the VOF multiphase model is used to investigate the motion and interaction of the existing phases.

The geometry of this model is designed in ANSYS design modeler® and is meshed in ANSYS meshing®. The mesh type used for this geometry is structured and the total element number is 12846.

Spillway Methodology

The simulation is performed in transient form in order to see the fluid motion over the spillway. Also, K-epsilon standard turbulence model is employed. The Volume of Fluid (VOF) multiphase model is used to model the phase, including the air and water-liquid.

Spillway Results

After the simulation process The contours of pressure, velocity, phases volume fraction, etc. are extracted and presented.

You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
