Qualified training movies and comprehensive CFD concept explanations, including setup, solution, results, and all perspectives of carrying out CFD simulations in Ansys Fluent.

Combustion

In project number 1, the Steady combustion of methane and air in a simple extended cubical combustion chamber is investigated. Radiation heat transfer must be considered since combustion chambers undergo extremely high temperatures. In this project, the mixture’s static temperature has a maximum value of 3500 k within the chamber. Methane and air enter the domain from inlets, in which methane is injected into the domain using only one inlet. Still, airflow is injected using two inlets due to achieve an approximately uniform mixture of fuel and air.

Project number 2 aims to model Simple Premixed Combustion in a Porous zone and see how a porous zone affects combustion temperature and stabilizes it. This simulation is a matrix-stabilized burner, and the results are compared to the same premixed combustion without porosity. the Species transport model has been used. gravity considered as -9.81 m/s-2 on the y-axis.

Project number 3 simulates the combustion process of methane gas in a vertical lime kiln. The construction of a vertical lime kiln consists of two main parts, including the combustion zone and the Preheating Zone. The fuel and air enter the building from the middle of the lime kiln and form a combustion reaction. As a result of the chemical combustion reaction, a significant amount of heat is produced, increasing the temperature inside the lime kiln.

In project number 4, we simulated the gas turbine combustion chamber using a discrete phase model (DPM) and species transport mode. In this case, the effect of spraying Benzene particles is done using the Eddy-dissipation combustion model. This combustion chamber is commonly used for jet engine users.

Given the increasing industrial use of coal consumption and the importance of finding clean energy coal technology development, modeling its combustion characteristics is very important. In project number 5, a combustion chamber is simulated. We used two-way DPM for particles and anthracite as an injection material has been used in this simulation. Anthracite is the best type of coal with the highest calorific value.

Spray Dryer (Species Transport)

In project number 6, we use two types of continuous and discrete phases. In fact, the hot airflow, which is responsible for evaporating the moisture contained in the solution, enters the spray dryer chamber as a continuous phase and flows into the chamber (Eulerian). At the same time, a solution containing water and solid particles (Lagrangian) injects into the chamber as a discrete phase. The main purpose of this simulation is to investigate the behavior of particles that flow as a discrete phase in a continuous flow.

Coronavirus

Project number 7 simulates the airflow from a patient’s (COVID-19) mouth in a Hospital room. In fact, in the present case, a special operating room has been designed that is equipped with ventilation and air conditioning systems. The main purpose of this simulation process is to allow fresh air (oxygen-carrying) to flow continuously into the interior of the room rather than to expel polluted air from the patient’s mouth to the environment. Ventilation systems and air conditioners are designed on the ceiling and floor.

Desalination (Species Transport)

Project number 8 investigates the performance of a step solar desalination unit. The present model consists of a small chamber with a sloping glass surface on both sides and steps within it, where saline water flows on the surface of these steps. Solar radiation heat transfer passes through the glass to the water’s surface in the enclosure to evaporate the water surface on the step walls. The resulting vapor meets the cold glass surface and undergoes a distillation process. Pure water from hot vapor distillation moves down the slope of the glass plate and discharges as pure water.

Gasification

Project number 9 simulates the gasification process inside a gasifier chamber. The gasification process is a set of chemical reactions in which a carbon-based substance is converted to carbon monoxide, hydrogen, and carbon dioxide. This process’s product is considered a renewable energy source with many industrial applications.

Multi-component (Species Transport)

In project number 10, the Multi-component particle type for droplets has been investigated. We used the one-way DPM to simulate the discrete phase.
