Opening Slide

Welcome to the spoken tutorial on Simulating 1D Conduction through a Bar.
Slide:

Learning Objectives

In this tutorial, we will learn to:
  • Set up a case of heat transfer in OpenFOAM
  • Simulate a conduction heat transfer case using a laplacianFoam solver
Slide: System Specifications To record this tutorial, I am using,
  • Ubuntu Linux Operating System version 22.04
  • OpenFOAM version 9
  • ParaView version 5.6.0, and
  • gedit Text editor

However, you may use any other editor of your choice.

Slide:

Prerequisites


As a prerequisite:
  • You should have basic knowledge of conductive heat transfer.
  • You should be familiar with setting up a case in OpenFOAM.
  • If not, please go through the prerequisite OpenFOAM tutorial on this website.
Slide:

Code Files

  • The files used in this tutorial are provided in the Code Files link on this tutorial page
  • Please download and extract them
  • Make a copy and then use them while practising
Slide:

Geometry

We will be solving a 1D Conduction Problem.
  • The bar is 1 metre long.
Slide: Geometry
  • The left face is maintained at a higher temperature compared to the right face.
  • The top and bottom faces of the bar are adiabatic.
  • According to the Fourier’s Law, we expect the flow of heat from left to right.
  • We will simulate this case using the laplacianFoam solver.
Only Narration Let’s look at the structure of laplacianFoam and how its equations are modeled.
Slide:

laplacianFoam

  • laplacianFoam is a basic OpenFOAM solver
  • laplacianFoam solves simple Laplace equations
  • An example of such an equation is thermal diffusion in a solid
Slide:

laplacianFoam

Highlight: Laplacian Equation

This is the equation implemented in laplacianFoam:

where,

  • alpha is the thermal diffusivity
  • T is temperature
Point to the equation. Let’s see how this equation is implemented in OpenFOAM
CTRL + ALT + T Open the terminal by pressing Ctrl, Alt and T keys.
[Terminal] Type:

cd $FOAM_SOLVERS

Type the following command and press Enter to move into the solvers directory.
[Terminal] Type:

cd basic/laplacianFoam

Type this command and press Enter to move into the directory of laplacianFoam.
[Terminal] Type: ls Type ls to view the files present in the laplacianFoam directory.
[Terminal] Type:

gedit laplacianFoam.C

Type the following command to open the source code for laplacianFoam.
[gedit laplacianFoam.C] Highlight:

Line no. 62 to 67

This is the code for solving the laplace equation in every timestep.
[gedit laplacianFoam.C] Highlight:

fvm::ddt(T)

The first term represents the time derivative for temperature field T.
[gedit laplacianFoam.C] Highlight:

fvm::laplacian(DT,T)

The second term represents the laplacian of temperature field T.

DT stands for thermal diffusivity.

[gedit laplacianFoam.C] Highlight:

fvModels.source(T)

The last term is on the right hand side of the equation.

It is used to add source terms to the equation.

Click on Close to close the gedit file. Let’s move on to the simulation.

You can now close gedit.

[Terminal] Type:

cd $FOAM_RUN

Type the following command and press Enter to move into the run directory.
[Terminal]: Ctrl + L Press Ctrl plus L keys together to clear the screen.
Only Narration Please remember to press Enter key after typing each command in the terminal.
[Terminal] Type: cp -r ~/Downloads/conductionBar . Copy the case folder that you had downloaded and extracted, into the run directory.
[Terminal] Highlight:


Downloads/conductionBar

In my system, the case folder named conductionBar is located in the Downloads folder.

The location of the case folder may be different for you.

Please use the appropriate command while copying the folder.

[Terminal] Type:

cd conductionBar

Let’s move into the case folder using the cd command.
Slide: Boundaries The computational domain has 4 boundaries, namely top, bottom, left, and right.

All 4 boundaries are fixed.

[Terminal Type]:

gedit system/blockMeshDict

The details of the mesh can be found in the blockMeshDict file in the system folder.


Type the following command to open blockMeshDict in a text editor.

[gedit blockMeshDict]

Point to vertices

These are vertices used to make a rectangular domain.
[gedit blockMeshDict]

Point to blocks

We have a single block with 20 cells only in the x-direction.
[gedit blockMeshDict]

Point to boundary

The two boundaries left and right are defined as type wall.

The boundaries topAndBottom and frontAndBack are kept empty as we are doing a 1D simulation.

[gedit blockMeshDict]

Click on Close to close the gedit file

Close the blockMeshDict file.
Slide:

Boundary Conditions

The boundary conditions used in the simulation are as shown in the table.
  • The left face is maintained at 373 Kelvin,
  • The right face is maintained at 273 Kelvin, and
  • The top' and bottom faces and front and back faces are of type empty, as we are running a 1D simulation.


Only Narration Let’s see how the boundary conditions are defined in OpenFOAM.
[Terminal] Type:

ls 0

The boundary conditions are defined in 0 folder.

Let’s view its contents.

[Terminal] Highlight:

T

You will see a temperature file.
[Terminal] Type: gedit 0/T Let’s open the temperature file, T.
[gedit - T] Highlight:

internalField uniform 273

The domain is initialized with a temperature of 273 Kelvin.
[gedit - T] Highlight:

bottom boundary condition

The left face is maintained at a constant temperature of 373 Kelvin.
[gedit - T] Highlight:

top boundary condition

The right face is maintained at a temperature of 273 Kelvin.
[gedit - T] Highlight:

“faces” “frontAndBack”

Since we are simulating a 1D problem, topAndBottom and frontAndBack are set to empty.
[gedit - T] Close the window Close the T file.
[Terminal] Type:

ls constant

Let’s now see the content of the constant folder using the ls command.
[Terminal] Highlight:

transportProperties

We can see the transportProperties file in the constant folder.
[Terminal] Type: gedit constant/transportProperties Let’s open the transportProperties file.
[gedit - transportProperties] Highlight:

“DT”

In the transportProperties file, we can see a property, DT.

DT stands for thermal diffusivity.

[gedit - transportProperties] Close the window Close the file.
[terminal]: type clear Clear the screen with the clear command.
Only narration Let’s simulate the problem in OpenFOAM.
[Terminal] Type: blockMesh First, let’s mesh the geometry using the blockMesh command.
[Terminal] Type: laplacianFoam Let’s start the simulation using the following command.
[Terminal] Highlight: End The simulation is now complete.
[Terminal] Type: paraFoam Let’s view the simulated results in ParaView.
[ParaView] Properties Tab

Click on Apply

Click on the Apply button to view the geometry.
[ParaView] Active Variable Controls


Click on vtkBlockColors >> Click on T

Let’s view the temperature contours for the simulation.


Click on the vtkBlockColors drop down in the Active Variable Controls and select T.


Ensure that you click on the T option with a point icon and not the box icon, in the drop down.

[ParaView] VCR Controls

Click on Last Frame

Let’s view the contours at the end of the simulation.

Click on the Last Frame button in the VCR Controls.

[ParaView] Layout Window


Point to Circulation

We can see the dissipation of heat from the hot end of the bar to the cold end.


The temperature changes linearly as we move from left to the right of the bar.


This is indicated as the color gradually changes from red to blue from left to right.

[ParaView]

Data Analysis => Click on plot over line filter


Now, let us plot the temperature along the length of the rod.


Click on the plot over line icon located on top of the screen as shown.

[ParaView]


Properties Tab => Click on x-axis


&&


Properties Tab => Click on Apply

Click on the x-axis and then click on the Apply button.


As we can see from the graph, the temperature variation is linear.

Only Narration With this we have come to the end of the tutorial.


Let’s summarize.
