TransAT Tutorial Manual 9.2. Forced Convection in an Isothermal Pipe

9.2 Forced Convection in an Isothermal Pipe

9.2.1 Prerequisites
• TransAT

• TransATUI

• Advanced Initial Conditions

• Paraview (or Tecplot)

9.2.2 Introduction

In this TransAT tutorial heat transfer owing to forced convection in an isothermal pipe is simu-
lated. User-defined functions are used to compute and output the following quantities to files:

• Bulk temperature and Nusselt number along the streamwise direction

• Velocity and temperature profile at the exit of the pipe along the crossflow direction

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

9.2.4 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 pipe, 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 pipe 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
now be selected to open the modules to set up a simulation with TransAT.
