3.2 Natural Convection in a Closed Cavity

3.2.1 Prerequisites

• TransAT

• TransATUI

• Paraview (or Tecplot)

3.2.2 Introduction

This TransAT tutorial provides a simple demonstration of the heat transfer that occurs when a
fluid flows inside a closed cavity which walls are heated. The setup is taken from simulations by
Theodoridis & Rasoul (2010)

3.2.3 Launch TransATUI
• Double-click the TransAT icon on the Desktop.

3.2.4 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 naturalconvection, 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 naturalconvection then click

After clicking , the Mesh & BCs tab will be opened.

The Geo, Mesh & BCs, Input and Execute tabs at the top of the TransATUI window can
