Description

Porous ANSYS Fluent CFD Simulation Training Package

This CFD training package is prepared for BEGINNER, INTERMEDIATE, and ADVANCED users of ANSYS Fluent software who are interested in the Porous modules, including 10 practical exercises. You will learn and obtain comprehensive training on how to simulate projects. The achieved knowledge will enable you to choose the most appropriate modeling approaches and methods for applications and CFD simulations.

Heat Transfer

Project number 1 simulates the airflow and heat transfer inside a cube-shaped chamber with a regular real porous medium. The porous medium used in this chamber is in the form of rows and columns of several aluminum balls, the number of which is 343. The main purpose of this study is to investigate changes in air temperature inside the chamber under the influence of these items as a porous medium.

In project number 2, the fluid flow and heat transfer inside a porous medium is investigated. This porous medium is in contact with a heat source, and the whole setup acts as a heat sink. The energy model is activated, and the RNG  k-epsilon model using standard wall function is exploited for fluid flow analysis.

In project number 3, Nano-fluid flow heat transfer in a porous medium heat exchanger is simulated and analyzed. The energy model is activated. Spalart-Allmaras model is activated for solving turbulent flow.

Multi-phase

Project number 4 simulates a three-phase flow mixture with a square cross-section within a channel. These three phases include air, water, and kerosene. In the initial state, only the airflow inside the channel is available and with the start of the simulation process, water flow enters the channel from the upper inlet section and kerosene flow from the lower inlet section. Therefore, to simulate multi-phase flow in the present model, the VOF multiphase model has been used. Also, inside the canal, a porous environment with a porosity coefficient of 0.1 is located.

Water infiltration (Porous)

Project number 5 simulates the infiltration of water flows into a cubic porous medium. In this modeling, a cube block is designed as a porous medium. The water flow enters it from a circular section at the bottom of the block. The porous medium defined in the block has a porosity coefficient equal to 0.01; This means that the ratio of empty space to the block’s total volume is equal to 0.01.

Ventilation

Project number 6 simulates the air conditioning inside a room where the transformers are located. Transformers are basically devices that can transfer electrical energy between two or more windings through electromagnetic induction, and as a result, a variable current in the primary winding of the transformer generates a variable magnetic field, which leads to the voltage produced in the secondary winding. In fact, these transformers are considered a kind of heat source that affects the ambient air temperature.

Biological Tissue

Project number 7 study examined blood flow in capillaries passing through a tissue containing cancerous tumors and using Hyperthermia Therapy. For this purpose, we assume a spherical space to be an example of healthy body tissue or cell in which blood flows at a very slow rate. There are several veins within this tissue. The vein structure of cells and tissues of the body are like bushes.

Fuel Cell (Porous)

Current collectors are made of solid material with thermal energy sources and electrical potential. The flow channels carry a mixture of gaseous species, including oxygen, hydrogen, and water. The catalytic part consists of a porous medium with a porosity coefficient of 0.5 and contains mass sources, thermal energy, electrical potential, proton potential, saturated water, hydrogen, oxygen, and water.  Project number 8 investigates the fluid behavior and thermal conductivity of a polymer fuel cell and its effect on the mass fraction of gaseous species and the amount of electricity produced in the cell.

Perforated Plate

In project number 9, we studied a perforated plate. Perforated plates have patterns of holes, slots, or decorative shapes. They have a wide area of usage in industrial applications, such as filters, silencers, radiator grilles, ventilation, or separator plates. Porous jump conditions are used to model a thin “membrane” with known velocity (pressure-drop) characteristics.

Porous Medium

In project number 10, ANSYS Fluent software investigates fluid flow through a porous medium with 3 different porosities. The fluid domain consists of an upstream flow domain, a porous medium domain, and a downstream flow domain. The standard k-epsilon model using the standard wall function is activated for solving fluid flow inside the computational domain.
