Eulerian Multiphase CFD Training Package, Beginners

Description

Eulerian Multiphase Model ANSYS Fluent CFD Simulation Training Package for BEGINNER Users

This training package includes 10 practical Multiphase Eulerian Model exercises using ANSYS Fluent software. MR CFD suggests this package for BEGINNER users who tends to learn the simulation process of Multiphase problems without any strong background.

Watery

In project number 1, a Numerical simulation of the Fountain Waterfall has been done. The system consists of two different fluids, including water as the primary fluid and one secondary fluid is Air. The Eulerian multiphase model has been used. The water is entering the fountain at a speed of 1 m/s with gravity considered as -9.81 m/s-2 on the y-axis.

In project number 2, a numerical simulation of water pouring out of the bottle is carried out. The TheEulerian model has simulated and solved the two-phase flow field equations. The Eulerian multiphase model allows for the modeling of multiple separate yet interacting phases. The phases can be liquids, gases, or solids in nearly any combination.

In project number 3, a numerical simulation of water spraying from the greenhouse roof has been done. The system consists of two different fluids, including Air as the primary fluid and one secondary fluid is water. The Eulerian multiphase model has been used. The jet-air is entering the domain with a speed of 0.3 m/s with gravity considered as -9.81 m/s-2 on the y-axis.

In project number 4, a numerical simulation of water from falling on resident water has been done. The goal of this project is to simulate raindrop impact on resident water. The Eulerian multiphase model has been used. The drop has an initial speed of zero, and gravity pulls it down. gravity considered as -9.81 m/s-2 in the y-axis.

Project number 5 simulates a watering process of lawns. The system consists of two different fluids, including Air as the primary fluid and one secondary fluid water. The Eulerian multiphase model has been used. The jet-air is entering the domain with a speed of 0.5 m/s with gravity considered as -9.81 m/s-2 on the y-axis.

Suppose any obstacle is placed on the fluid flow path. In that case, it causes the fluid level to rise behind it and increase its velocity, which eventually leads to fluid overflowing on the obstacle. These obstacles are regarded as weirs. Weirs have different uses depending on their shape and are mostly used in civil engineering. In project number 6, the three-phase flow of water, Air, and sand flows over a circular weir is simulated.

Industrial Application (Eulerian Multiphase Model)

The goal of project number 7 is to simulate sludge flow settling in a pipe. The Eulerian model has been used. The water is entering the domain with a speed of 0.01 m/s with gravity considered -9.81 m/s-2 on the y-axis.

Project number 8 simulates two-phase flow as soluble particles in a given fluid in a channel with a convergent-divergent structure. The Eulerian multiphase model has been used to simulate the present model. The Eulerian multiphase model is considered the most complex model for defining multiphase flows. In this simulation, the type of particle dispersion in the base liquid is defined in granular form, and the particle diameter is defined as 0.00002 m. The base fluid and its soluble particles enter this channel at a rate of 0.007142 m.s-1

Project number 9 simulates gas-solid flow within a fluid catalytic cracking (FCC) system. These FCC systems have many applications in chemical process units that are used to optimally convert high-boiling oil ratios to lighter high-value products. Inside the FCC reactor, two important separate areas are defined, including a dilute area called the disengager and a dense area called the stripper.

Moving Cylinder

Project number 10 consists of two different fluids, including water as the primary fluid and one secondary fluid. Therefore, the Eulerian multiphase model has been used to define the flow of two fluids in the system. The two-phase flow enters the chamber in the form of a hollow cylinder.
