Chemical Engineering ANSYS Fluent Training Package, for INTERMEDIATE

Description

Chemical Engineering ANSYS Fluent Training Package, 10 Practical Exercises for INTERMEDIATE Users

This training package includes 10 practical exercises, using ANSYS Fluent software. MR CFD suggests this training package for all Chemical engineers, who will learn CFD simulation in this field at the INTERMEDIATE level.

Chemical Engineering

In practical exercise number 1, numerical simulation of bubble motion under the water on a plate with and without shear stress has been done. The VOF model has been used to simulate and solve the two-phase flow field equations. The purpose of this project is to consider the effect of surface tension in simulations where the free surface in phase is investigated.

Practical exercise number 2 simulates a Packed Bed Reactor. Packed bed reactors, also known as fixed-bed reactors, are often used for catalytic processes. A packed bed reactor (PBR) is preferred for heterogeneous reactions, where the solid-fluid contact dramatically influences reaction rate.

In project number 3,  the reverse osmosis mechanism is simulated. This mechanism is used to purify water so that a membrane is placed in front of the saline movement and does not allow the salts in the water to leave and pure water leaves. Eulerian Multiphase model has been used in this project.

Practical exercise number 4 simulates hydrate formation flow inside a tube with a 90-degree elbow. Hydrates are organic substances that contain water. Hydrates are formed by adding water. The hydrate in this project is a combination of three different materials of water, water vapor, and methane.

Separator

In analysis number 5, the process of separating the liquid phase from the gas using a horizontal cylindrical separator is investigated. The realizable k-epsilon model is used for solving turbulent flow equations. Also, a multi-phase VOF model is activated to simulate two phases of oil and hydrogen sulfide inside the separator. Problem number 6 simulates the collision of air and water flow within a separator chamber. In this modeling, a cylindrical separator chamber is designed whose interior space is full of water. Water then enters through a vertical pipe from the top of the chamber and exits through a bottom pipe located at the bottom of the chamber; While airflow enters from a horizontal tube on the lateral surface of the chamber and exits through a horizontal tube on the lateral surface of the upper part.

Mixing

Problem number 7 simulates fluid mixing in a bioreactor with a Rushton turbine. Bioreactors are equipment and systems in which biochemical reactions occur and are used in various industries, including pharmaceutical, food, biochemical, perfumery, chemical, etc. The bioreactor modeled in this simulation has a cylindrical structure. Practical exercise number 8 simulates the mixing of two substances including carbon dioxide and ethanol in a rectangular tank. The VOF multiphase model has been used to simulate the present model. The constituents of this process include carbon dioxide with a molecular weight of 44.00995 kg.kmol-1 and ethanol with a molecular weight of 28.966 kg.kmol-1.

Cyclone

In project number 9, the motion of particles in a cyclone has been simulated. We used the one-way DPM to simulate the discrete phase (particles). A cyclone is a device used to separate particles from gas and has many applications in the chemical industry. Finally, in practical exercise number 10, the motion of particles in a Fly Ash Cyclone has been simulated. The Eulerian-Lagrangian technique is applied in the cyclone separator simulation. In this approach, the gas is treated as a continuum, and individual solid particles are tracked through the flow field by Lagrangian tracking to determine their position. In cyclone separators, the drag and gravity forces are considered significant due to the large ratio of the gas/particle density.
