Question

Asked 31st Dec, 2017

I am planning to simulate a turbulent flow with a relatively low Reynolds number using LBM, can anyone recommend a suitable open source code? OpenLB or Palabos or others?

Thanks!

Is there any update to this discussion? What is the current state of development for these open LBM softwares?

Looking at the capabilities, Palabos emerges as the most versatile, supporting free surface flow, multiphase flow and permeable media.

Hello

Professor Jos Derksen, has developed a very efficient FORTRAN LBM code.

We used it and it works.

Here is his last paper :

Dear Mister Xu,

There is this nice code from Erlangen (Germany) called waLBerla.

You can find the details here: http://walberla.net/

Among the two i think Palabos is more stable one. There is a book authored by Prof A Mohammad. Few basic codes are given there. I recommend you start with that.

OpenLB has accurate turbulence models implemented, some in joint work with PhD students of Adams (TUM). The results has been published and validation examples are provided.

Next February there will be a Spring School on LBM and OpenLB (cf. www.openlb.net/spring-school-2019). There, you will get help getting started with the code.

It depends on the problem that you have in hand. Both OpenLB and Palabos are excellent codes. If you have a complex geometry that requires large computational resources, then following codes might also be worth looking at:

- Musubi: https://bitbucket.org/apesteam/musubi
- WalBerla: http://www.walberla.net

http://exolete.com/lbm/ has also nice 2D/3D codes for learning purposes.

As previously stated, depends on your targets. For example, when I was looking for multicomponent model I found it in OpenLB.

Also, the good thing about OpenLB is that it outputs VTK format which is possible to visualize in ParaView. I am not sure if you can do it with Palabos.

In this paper, two sub-grid scale (SGS) models are introduced into the Lattice Boltzmann Method (LBM), i.e., the dynamics
SGS model and the dynamical system SGS model, and applied to numerically solving three-dimensional high Re turbulent cavity flows. Results are compared with those obtained from the Smagorinsky model and direct numerical simulati...

The effects of shear flow on droplet collapse during the coarsening process in a vapor–liquid system are investigated by a free energy lattice Boltzmann model. To simulate different viscosity ratios, a local relaxation time parameter is integrated with LBM algorithm. The results show that for zero and small shear rates, droplet coarsening happens i...

Large eddy simulation (LES) of a turbulent flow over two cubic prisms is performed based on the Lattice Boltzmann Method (LBM). Two wall-mounted cubic prisms are arranged in tandem on the bottom wall of a fully developed turbulent channel flow for a Reynolds number of Re H = 4000 (based on the centerline velocity, U c , and the prism height, H).
