TransAT Tutorial Manual 1.3. Flow over a Cylinder (Re=20)

1.3 Flow over a Cylinder (Re=20)

1.3.1 Prerequisites

• TransAT

• TransATUI

• Paraview (or Tecplot)

1.3.2 Introduction

A single-phase flow over a cylinder is simulated here where the Reynolds number is Re = 20.
The flow can be simulated using a steady simulation. This tutorial is beneficial to understand
the basics of multiblock meshes

• Dimensions of the domain are 30m × 30m resolved by a mesh of 72 × 72 × 1 cells.

• The cylinder with a radius of 0.5m is located in the middle of the domain.

• The fluid over the cylinder is air.

1.3.3 Launch TransATUI

• Double-click the TransAT icon on the Desktop.

1.3.4 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 cylinder, then click to create the folder

• Click to select the folder and close the browser

• Set Project Name to a more explicit name such as cylinder then click
