# Problem Definition
The problem is to simulate a Rotary Air-Lock Valve. The external diameter of rotor is about 21 cm. There is one type of particle in this simulation. Particles are inserted into the inlet of the valve from t=**0** s.
The problem is to simulate a RotaryAirLockValve. The external diameter of the rotor is about 21 cm. There is one type of particle in this simulation. Particles are inserted into the inlet of the valve from t=**0** s.
* **28000** particles with **5 mm** diameter are inserted into the valve with the rate of **4000 particles/s**.
* The rotor starts its ortation at t = 1.25 s at the rate of 2.1 rad/s.

# Setting up the Case
As it has been explained in the previous simulations, the simulation case setup is based on text-based scripts. Here, the simulation case setup files are stored into three folders: `caseSetup`, `setting`, and `stl` (see the above folders). See next the section for more information on how we can setup the geometry and its rotation.

### Insertion of Particles
Insertion of particles starts from t = 0 s and ends at t = 7 s. A box is defined for the port from which particles are being inderted. The rate of insertion is 4000 particles per second.

# Performing simulation and seeing the results
# Performing simulation and viewing simulation results
To perform simulations, enter the following commands one after another in the terminal.
Enter `$ particlesPhasicFlow` command to create the initial fields for particles (here the simulaiton has no particle at the beginning).
Enter `$ particlesPhasicFlow` command to create the initial fields for particles (here the simulation has no particle at the beginning).
Enter `$ geometryPhasicFlow` command to create the geometry.
At last, enter `$ sphereGranFlow` command to start the simulation.
After finishing the simulation, you can use `$ pFlowtoVTK` to convert the results into vtk format stored in ./VTK folder.
Finally, type `$ sphereGranFlow` command to start the simulation.
After the simulation is finished, you can type `$ pFlowtoVTK` to convert the results to vtk format, which can be found in the ./VTK folder.
