TransAT Tutorial Manual 6.2. Counter current flow in a pipe

6.2 Counter current flow in a pipe

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

6.2.1 Prerequisites

• TransAT

• TransATUI

• Advanced Initial Conditions

• Paraview (or Tecplot)

6.2.2 Introduction

In this test case, a stratified air-water countercurrent flow will be simulated. Air flows at a tem-
perature of 298.15K and water flows in the opposite direction at a temperature of 295.15K.

An image of the domain is given in Fig 6.8. In the top half of the pipe, air flows from right
to left with an inflow velocity of 4 m/s, while water flows from left to right with a velocity of 0.1
m/s in the bottom half.

This tutorial is beneficial in understanding the creation of a two-phase problem and the
definition of a domain with complex inflows and outflows.
