Simulations & Interactive Tools

    1. PhET simulations Physics
    2. Fluid flow simulation developed by  Prof. Daniel Schroeder, Physics Department, Weber State University. You can visualize how fluid flows around objects of different shape, for example, an aerofoil or spoiler. You may change fluid properties as well. Click HERE  to go to the simulation. (It runs on Chrome, Firefox, and Opera browsers). Prof. Schroeder also teaches how to make such applets yourselves (CLICK HERE).

     

    Advanced simulations for Projects

    1.  Flowsquare  is a free two-dimensional computational fluid dynamics (CFD) software for unsteady, non-reactive/reactive flows. The aim of this software is to provide a handy CFD environment so that more people can get to know what CFD is like and simulate flows for their educational and/or academic interests. 

     

    1. OpenFOAM  is an open-source software used as a platform to perform steady-state and transient numerical simulation of fluid flow. The tutorials are also available for free.
