Species Transport CFD Simulation Package, ANSYS Fluent Training for ADVANCED Users
This CFD training package is prepared for ADVANCED users of ANSYS Fluent software in the Species Transport area, 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.
Project number 1 simulates the biomass combustion process inside a gasifier chamber. The material used for combustion is biomass, which reacts with the oxidizer. It is a biomass substance made from wheat straw that reacts with oxygen to produce synthetic gas as a healthy fuel. In the present model, fuel containing biomass and air enters the chamber from two separate inlets from the upper area. It creates a mass of materials, including ash and semi-combustible coal, in the lower part of the chamber.
In project number 2, we have simulated a non-premixed one stream combustion using the PDF model (probability density function). A two-dimensional channel is drawn in this project as a combustion chamber. Air enters the channel at a speed of 1 meter per second and a temperature of 650 Kelvin. Pentane fuel is injected into the canal in liquid droplets with a diameter of 100 microns and a temperature of 300 K in a solid cone of 45 degrees with a flow rate of 0.004 kg / s. The channel wall temperature is 1200 Kelvin.
In project number 3, Hypersonic Combustion in a Scramjet engine with Viscous is simulated. The Mach number of inlet air is set to 6, and the temperature of the whole domain equals 300k. At the middle part of the nozzle, in which Mach number reaches 1, hydrogen injects into the flow with a Mach number of more than 1, and consequently, the combustion will occur in the nozzle.
In project number 4, which has been done by CFD numerical simulation method, The spray drying chamber is simulated by the two-way DPM & Species Transport model. The particle diameter is 1 mm, and the flow moves at one m/s.
In project number 5, a rice drying device has simulated using the Two-way Discrete Phase Model (DPM) & Species Model, and then the results were investigated. Hot air enters the drying device, and then 120000 rice grains with 10% moisture are injected randomly for 6 seconds. The evaporation process continues for 9 seconds after complete injection. Furthermore, the hot surfaces are in contact with the hot exhaust smoke of the engine, which provides an efficient condition for the drying device.
In project number 6, a revolving rice dryer device was simulated using Evaporating droplets with a one-way DPM model, and then the results were investigated. Hot air enters the rice dryer through the holes on a porous tube located at the center of the enormous chamber. About three million rice particles are injected with 15% moisture droplets into a chamber revolving with 100rpm angular speed.
Project number 7 is about the rocket engine nozzle. A rocket engine nozzle is a type of propellant nozzle; This means that the internal energy of the gas is converted into a driving force and forms a high-velocity fluid jet. This nozzle is used in rocket engines to expand and accelerate the combustion gases produced by burning fuels in propellants. The exhaust gases exit the nozzle at supersonic speed.
In project number 8, ANSYS Fluent software stimulated an industrial Furnace numerically. The furnace simulated in this project is combusted with methane fuel to heat the Methane in the pipes so that the Methane can be moved more quickly and with less force. By observing the results, it can be seen that the outlet temperature of methane pipes has increased compared to the inlet temperature.
Population Balance Model (PBM)
Project number 9 simulates the production process of Calcium-Oxalate based on the Population Balance Model (PBM). In this project, the calcium-oxalate production process is modeled, and then the PBM is analyzed using the production, growth, and displacement of production particles. The mechanism of the studied system is such that the flow of water carrying calcium and oxalate enters a chamber through two pipes.
Project number 10 investigates the spraying of Air fresheners in the restroom by the Two-way DPM method. According to this definition of injection, fragrance particles are physically expelled from the device by water droplets that evaporate in space. These droplets have a temperature of 310 K, a velocity of 50m.s, and a mass flow of 0.018 kg.s-1, which are emitted at intervals of 0s to 0.1s. The particle diameter is not constant during diffusion, and the rosin-rambler-logarithmic distribution method is considered for the diameter of the Particles.
You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
