In this DEM simulation, we create a random packed bed of spherical particles in a cylindrical container with the diameter of 15 cm and height of 20 cm. Particles are a mixture of spherical particles with similar density (2500 kg/m3) and uniform sizes distribution between 3 and 7.5 mm. In…
In this simulation, we create a random packed bed of particles (packed bed of spheres) in a cylindrical container with the diameter of 15 cm and length of 20 cm. To create this bed, 8000 7-mm spherical particles with the density of 2500 kg/m3 are used. In the followings, we…
High density polyethylene is produced by polymerizing ethylene (HDPE) and in cases co-polymerizing with propylene and 1-butene to achieve the desired density and properties. Hydrogen is also used to control average molecular weight of the polymer. One industrial process for producing HDPE is slurry phase reactor. Hexane is used as…
You will learn how to use reactingFOAM solver to simulate a turbulent combustion of methane in air. The simulation is based on the combustion of methane in the Sandia D flame benchmark. reactingFoam is a transient solver for simulating compressible, laminar/turbulent reactive systems. This solver uses stoichiometry expressions and kinetic…
In this post you will learn how to install OpenFOAM v2006 from source pack. The operating system is Ubuntu 18.04 LTS. It is assumed that you are installing OpenFOAM v2006 on a fresh operating system. These steps were also followed for installing OpenFOAM v2006 on Ubuntu 20.04 LTS. Note: If…
You see an OpenFOAM simulation of a single phase stirred tank reactor using AMI technique. This simulation is performed to find the residence time distribution (RTD) in a stirred tank reactor. In the design and scale-up of chemical reactors, the residence time distribution of fluid particles inside the reactor should…
In this tutorial you will learn how to setup a particle tracing system to obtain the residence time distribution of flow in a T-channel. This method can essentially be applied in conjunction with any incompressible solver, like icoFoam, pisoFoam, pimpleFoam and etc.
In this post you will learn how to install OpenFOAM v1912 from source pack. The operating system is ubuntu 18.04 LTS. It is assumed that you are installing OpenFOAM v1912 on a fresh operating system. A) Download and Initial Checks 1) Downloading source code: go to official website of OpenFOAM…
In many occasion in process industries (i.e. chemical engineering), we need to create a random packed bed of Catalysts. Packing of Hollow Cylinders in reactor (heterogeneous catalytic reaction) tubes can be simulated using DEM. This packing will then be used in other reactor flow simulations for more detailed kinetics, heat…
Many industrial processes like granulation, particle coating, bio-mass pyrolysis, dryers contain rotating drum as a part of their processes. its rotation cause a gentle motion of particles. So, this gentle motion brings particle to the bed surface, where particles avalanche from top to bottom. The drum wall pulls particles up…
