4.5 Spillway

Please note: this tutorial makes use of Advanced Initial Conditions. Microsoft SDK is required
to run it.

4.5.1 Prerequisites

• TransAT
• TransATUI

• Advanced Initial Conditions

• Paraview (or Tecplot)

4.5.2 Run time

Approximately 20 minutes using 4 core processor when run in parallel.

4.5.3 Introduction

In this tutorial, a pipe spillway is simulated. Algebraic Slip Model is selected for modelling
interphase physics. It is assumed there is a slip between two phases (water and air here) resulting
in two different phase velocities. The goal of the simulation is to investigate in water discharge
rate over the spillway.

4.5.4 Launching TransATUI
• Double-click the TransAT icon on the Desktop.

4.5.5 Opening TransAT window

The first step in creating a new TransAT project is naming said project and giving it a location.

• Click to create a new project

• In the next window, navigate to the folder where the project will be saved

• To create a new project folder, click in the top right corner of the window

• Enter a project folder name, say spillway, then click to create the folder
