Mixing of particles in V-blender
The video shows the DEM simulation of a V-blender wherein small and large particles are being mixed during rotation of the blender. Simulation was performed using open-source code, PhasicFlow, which can be found on github. It is a parallel code that can be run on CPU or GPU.

Combustion of Methane in the Flare (LES simulation)
มุมมอง 1.2K3 ปีที่แล้ว
You see a #LES simulation of methane #combustion in a flare. The simulation has been performed using #OpenFOAM and visualized by #Paraview. The animation speed is 0.5x. for more information visit: www.cemf.ir/methane-combustion-in-a-flare/
Particle Tracing for Residence Time Distribution (RTD) in a Stirred Tank Reactor
มุมมอง 3.4K3 ปีที่แล้ว
A pulse injection (1 second) of 10000 inert particle tracers is injected into the reactor from top inlet and the concentration of particles at the outlet is measured to obtain RTD. The simulation was performed by OpenFOAM, and the visualization by ParaView. More details on: www.cemf.ir/residence-time-distribution-rtd-in-stirred-tank-reactor-openfoam-simulation/
Packing of Hollow Cylinders in a Tube
มุมมอง 3323 ปีที่แล้ว
You see how a random packed bed of hollow cylinders is formed. This simulation has been done using discreteFlow code, which is a DEM code. For more details visit: www.cemf.ir/packing-of-hollow-cylinders-cemf/
V-Blender DEM simulation
มุมมอง 1.7K4 ปีที่แล้ว
This is a DEM simulation of a V-Blender. The rotation speed of the blender is 30 RPM. The simulation has been performed using an in-house code developed in Center of Engineering and Multiscale Modeling of Fluid Flow. For more information visit: www.cemf.ir/v-blender-a-dem-simulation/
Bubble column simulation using CFD
มุมมอง 1.5K4 ปีที่แล้ว
You see a 2D simulation of a bubble column using OpenFOAM(R) Superficial air velocity is 0.05 m/s . Column diameter is 0.26 m. Column height is 2 m. The simulation was performed using twoPhaseEulerFoam solver. The video is created using Paraview For more info: www.cemf.ir/bubble-column-an-openfoam-simulation/
Eulerian Simulation of a gas-solid fluidized bed
มุมมอง 1.1K4 ปีที่แล้ว
You see the fluidization of Geldart Group B particles in a gas solid fluidized bed with air at ambient conditions. Bed dimensions: 150x28x2.5 cm3. The simulation was done using twoPhaseEulerFoam of OpenFOAM. Rendering was performed by Paraview. For more information visit: www.cemf.ir/a-gas-solid-fluidized-bed-simulatoin/
DEM simulation of the inclined screw conveyor
มุมมอง 132K4 ปีที่แล้ว
You see the conveying of solid particles to higher elevations by an inclined screw conveyor. The results are obtained based on the discrete element method (DEM) simulations. The simulations were performed using an in-house parallel code developed in C . Screw diameter: 12 inches rotation speed: 75 RPM For more information visit: www.cemf.ir/screw-conveyor-a-dem-simulation/
Mixing of non-spherical particles in a drum mixer
มุมมอง 1.6K4 ปีที่แล้ว
The drum rotates 12 rpm and its radius is 0.25 m. The results are obtained based on the discrete element method (DEM) simulations. The simulations were performed using an in-house parallel code developed in C . Paraview was used for visualization of the results.

بسیار عالی
Now explain to me how you will make this zero gap between screw and pipe? Normally 1/2" gap is considered in real world.
great presentation, however how do simulate particles that is non shape like ground meat mixture for the simulation of my mixer? Thank you if this message will reach to you
Sir, can we convey wet coffee fruit skin
What programs do you wear it for make a screen conveyor animation
Kahan se hain aap Humko Ek chahie
Great, I interesting in developed a tubular conveyor with python you have an idea, the challenger for me is the force in cohesion
Nice presentation sir...is it possible to convey materials with 50mm particle size? I am from a PVC manufacturer...our objective is to find out a screw conveyor which can convey large particle crushed PVC. thanks.
What is program 3d
JE VOULAIS COMPRENDRE LE PRINCIPE DE SIMULATION, et si vous fixez la température et le CO2 et vous visualisez la combustion?
Which software you used in simulation
OpenFOAM
Can you tell us which OF version and solver you are using?
It was a year ago. If I correcrly remember, it was OF-v7 and the solver was reactingFoam. You can do the same with of-v1912 or later.
Perais keya he iska
Great video.. could you make a video on gas-liquid-solid process ..
Hi Hamid, thanks for uploading the video. Quite useful to understand parcel tracing in openFoam. Can you further elaborate the method in detail to measure RTD from the generated data ? Or If you have you uploaded this procedure anywhere, please share the link.
Great clear demonstration of the auger. I tried this in Blender with rigid bodies, but this is very nice. Thanks.
Nice Video Sir.. Sir I have a one question. For Screw Conveyor Capacity calculation taking 1/4 th area of screw dia is it ok?
NICE!!!
salem Can you send me a design
Hello Dr. Hamid, how to make Paraview represent non-sperical particles (eg. superquadric particles) ? I made a model using LIGGGHTS software with superquadric particles but Paraview is representing them as spherical !
Hi, they are stl surfaces.
I think there is a plugin available now to visualise superquadric vtk files generated by LIGGGHTS in Para view
Hi Hamid Reza,excellent presentation and just visited your website.we do require very often to perform SIMULATIONS prior to production start of our SCREW CONVEYORS.We design and fabricate screw conveyors serving a vast range of industries (custom tailored according to clients EDS).kindly send your email address enabling us to communicate further.kind regards
Hi, I cannot provide email address in a comment to protect my inbox from spam emails. Just follow this link address. www.cemf.ir/center-of-engineering-and-multiscale-modeling-of-fluid-flow/contact-cemf/
@@Hamid1Reza Hi, i have sent you a request by following your link.kindly confirm its receipt .regards
Why do you need to perform simulation ??
Hi, may you tell me how can i view the flow with spheres in paraView? ; i tried but couldn't. Regards.

hi, i checked the website and there were several tutorials with the simulation files, would there be any chance that they would upload this simulation
in near future.
