Hydraulic Structure & Civil ANSYS Fluent Training Package, 10 Practical Exercises for INTERMEDIATE Users

This Training Package includes 10 practical exercises that are numerically simulated by ANSYS Fluent software for INTERMEDIATE users in the field of Hydraulic Structures and Civil engineering.

Weir & Spillway

In practical exercise number 1, the Eulerian three-phase flow of water, air, and sand flowing over a circular weir is simulated. The water will enter the computational domain with a velocity of 1m/s and it flows over the sand bed behind the weir. The water flow will lift some of the sand and carry it as it flows over the weir.  In project number 2, the two-phase flow of water and air flowing over an ogee spillway is simulated. The water will enter the computational domain with a mass flow rate of 60 tons/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.

Hydraulic Jump

In practical exercise number 3, the hydraulic jump of water flow is analyzed. The VOF approach is utilized to efficiently simulate the water flow inside ambient air. Hydraulic jump is of great importance in agricultural applications and open channel flows where water flow, after a certain distance which can be solved for using the analytical equation, undergoes a significant decrease in velocity and increase in flow height.

Dam & Cascade

Numerical simulation of lifting dam has been performed in project number 4. The model is used to simulate two fluid phases, and the purpose of this project is to investigate the changes in the free surface of the fluid over time. Two models are reviewed in this project. In the first model, the flow continues its path after crossing the dam, but in the second model, it encounters an obstacle. The goal of project number 5 is to simulate a cascade with an interrupted water inlet. The Eulerian multiphase model has been used. The water is entering the domain with the speed of 0.3 m/s with gravity considered as -9.81 m/s-2 on the y-axis.

Turbine

Problem number 6 simulates the water flow inside a Francis water turbine. A water turbine is a turbomachinery that converts kinetic energy from water flow or potential energy from water height differences into rotational motion. Francis turbines are one of the types of water turbines that have the ability to use both kinetic and potential energy for power generation at the same time due to the location of their blades. In project number 7, the water flow passing over the Kaplan turbine is investigated. The Kaplan turbine rotates at 3300 rpm and sucks the water in. RNG k-epsilon model is exploited to solve turbulent flow equations. It should be noted that the MRF (Frame Motion) option has been activated to model the rotation of the turbine.

In practical exercise number 8, we are going to study the hydrodynamics of the Kaplan turbine. The geometry included a small size Kaplan turbine with 125 [mm] as a new prototype. Our static domain consists of 8 [m] long rectangle, and our rotary domain is the Kaplan geometry with 16.5 RPM as the angular velocity. In project number 9, an Archimedes Screw Turbine (AST) consisting of 3 blades is simulated in two models. The first model is unsteady Frame Motion, and the second one is an unsteady Mesh Motion. Considering the conception of both methods, the turbine in the frame-motion method is in a stationary state, and the fluid around it is rotating, while in the Mesh Motion method, the rotating zone that contains the Screw Turbine rotates independently.

Open Channel

finally, in analysis number 10, the flow inside an open channel which has a 180-degree bend, with a side outlet is investigated. The standard k-epsilon model is used for solving turbulent flow equations. Also, a multi-phase VOF model is activated to simulate two phases of water and air inside the canal.

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