Use this blockMeshDict to automatically create a structured mesh for cylinder given the radius, height and average cellSize for the final mesh. There will be 3 boundary patches for you in the final mesh: inlet, outlet, and cylinerWall. You also have the option to make the inner square curvy-like by…
Category: OpenFOAM
OpenFOAM is an open-source CFD packages that is used for modeling of fluid flow. The solvers cover compressible, incompressible, reacting, non-reacting, single phase and multiphase flows with resolved interface (VOF) and unresolved phase interface (Eulerian). It also provides some powerful meshing technologies like snappyHexMesh for meshing complex geometries. Here, you will see all the contents related to OpenFOAM.
How to install OpenFOAM on Windows 10 & 11
To get the best experience with OpenFOAM installation on windows, you need to have windows 10 (build 19041 and higher) or higher versions of Windows like windows 11. So, you can install/activate WSL2 on your computer. WSL, stands for windows subsystem for Linux, is a new technology of Microsoft and…
How to install OpenFOAM-9
In this tutorial, you will learn how to install OpenFOAM-9. If you already have some components installed on your computer, you may skip some of the steps. This tutorial has been tested on Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. Two main methods is introduced here: 1)…
Methane Combustion in a Flare
Excess, unrecoverable hydrocarbons are collected and burnt (in a flare) before releasing to atmosphere to reduce their environmental impact. Millions tones of hydrocarbons are burnt each year all around the world. A survey shows that, in 2017, around 270 million tones of CO2 is emitted by flaring. In many industrial…
How to Install OpenFOAM v2012 from Source Pack on Ubuntu
In this post you will learn how to install OpenFOAM v2012 from source pack. The procedure is tested on Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. It is assumed that you are installing OpenFOAM v2012 on a fresh operating system. Note1: If you previously installed the older version of OpenFOAM…
reactingFoam: How to simulate combustion of a flame by OpenFOAM
You will learn how to use reactingFOAM solver to simulate a turbulent combustion of methane in air. The simulation is based on the combustion of methane in the Sandia D flame benchmark. reactingFoam is a transient solver for simulating compressible, laminar/turbulent reactive systems. This solver uses stoichiometry expressions and kinetic…

Residence Time Distribution (RTD) in Stirred Tank Reactor: OpenFOAM Simulation
You see an OpenFOAM simulation of a single phase stirred tank reactor using AMI technique. This simulation is performed to find the residence time distribution (RTD) in a stirred tank reactor. In the design and scale-up of chemical reactors, the residence time distribution of fluid particles inside the reactor should…
Residence Time Distribution by Particle Tracing
In this tutorial you will learn how to setup a particle tracing system to obtain the residence time distribution of flow in a T-channel. This method can essentially be applied in conjunction with any incompressible solver, like icoFoam, pisoFoam, pimpleFoam and etc.
