Computational Fluid Dynamics (CFD) and Matlab?

I'm wondering: If I wanted to illustrate the 2D/3D air-flow and turbulence around simple solid objects which I define myself, would that be possible in Matlab? Cheers Jakob

Is there a matlab code for transtonic small disturbance equation? Thank you.

You may check out the QuickerSim CFD Toolbox for MATLAB. It is a third-party toolbox for solving fluid flows in the MATLAB environment. You can create heat transfer and fluid flow simulations in 2-D and 3-D.

The toolbox provides the user with efficient CFD solvers and auxiliary (e.g. mesh-manipulation, preprocessing, and postprocessing) functions inside of MATLAB. It encourages users to make use of them in combination with their own code.

You can check out the free code or ask for a trial full verion here.

[Precise Simulation]

The FEATool Multiphysics toolbox (available via the FileExchange and MATLAB Add-Ons) allows you to perform fluid flow and other physics simulations directly in a GUI environment. In addition to using the built-in GUI you can also use all toolbox functions directly on the command line, so in your case you could use featool m-functions for just geometry and grid generation, or 3D visualization and postprocessing as in the linked post.

The linked video tutorial show how to set up and solve a flow around a cylinder directly in MATLAB and optionally solve it with the external OpenFOAM CFD solver.

Yes, MATLAB can be used to visualize data for turbulent flows. One of the examples would be the MATLAB code available on the Johns Hopkins Turbulence database website: Using the JHU Turbulence Database Matlab Analysis Tools. This GUI based implementation "provides functionality for plotting/animating velocity and vorticity fields, computing and plotting longitudinal energy spectra, and computing PDF's of velocity, pressure, and velocity increments". Here is one of the snapshots I could produce at my end.

Here, the data is fetched from the JHU Turbulence Database Cluster. You can write a similar code to visualize your own data.

Thank you very much for your help! Will get straight into playing around with this!
