Coronavirus (COVID-19)

In project number 1, Ansys Fluent software used two-way DPM to simulate human Cough virus particles in the Coffee Shop. According to this definition of injection, human cough virus particles are physically expelled from the patient’s mouth by water droplets evaporating in space. Following this method and the suitable formulation, the values related to the minimum, maximum, and average diameter size determine the exponential parameter of the spread and the number of diameters per injection. It should be noted that the drop mode is applied when the species transport model is also activated.

The purpose of project number 2 is to investigate the ability of coronavirus particles to spread inside the Bank from a bank customer to a healthy bank employee. This simulation process is performed in two different modes. In the first modeling, no cover is located between the client and the bank employee to show the virus’s transmission power. In the second model, an attempt is made to make a thin plastic cover between them. For the present simulation, the discrete phase model (DPM) is used; Because this model allows us to study a mass of particles discretely or bit by bit in a continuously fluid space.

The Elevator Cabin is one of the most important spaces in the discussion of coronavirus disease; Because usually, some people with the shortest possible distance are placed in a small space with a not very strong ventilation system. In project number 3, based on the CFD method, an attempt has been made to simulate the coronavirus particle dispersion from the carrier patient’s cough inside an elevator cabin.

The purpose of project number 4 is to investigate the diffusion power of virus particles inside the Car. For the present simulation, the discrete phase model (DPM) is used; Because this model allows us to study a mass of particles discretely or bit by bit in a continuously fluid space.

Combustion (Species Transport)

Project number 5 is about the combustion inside a Boiler. Boilers are pressurized tanks that carry out the boiling or heating fluid. Boiling is a process that brings the temperature of a fluid to the boiling point. Therefore, the combustion reaction must occur inside these boilers. The combustion reaction occurs in the computational zone of the boiler, and the desired species are defined using the species transport model. Nine different species are defined to define the combustion reaction, and five combustion reactions between these species are defined as Volumetric.

Project number 6 is the CFD simulation of combustion in a bluff-body mild burner. In fact, a burner is a device that combines a certain amount of air with fuel in a safe space, converting fuel energy into heat energy, which also produces some gas as a result of this combustion process. The flame produced in the burner is transmitted to the interior of the chamber by two methods of convection and radiation. Therefore, the Radiation (DO) model should also be used in the present model. Also, since the combustion process takes place within the combustion chamber, the species Transport model is also used.

Project number 7 simulates a two-step mechanism of combustion in a gas flare in the presence of wind flow. The flare system, also known as a gas flare, is a combustion device used in industrial units such as oil and gas refineries and the production of oil and gas wells, especially on offshore platforms. Gas flares are responsible for burning the natural gases released during oil extraction in a completely controlled manner.

Fuel Cell

Project number 8, which has been done by CFD numerical simulation method, A fuel cell is simulated. Fuel cells generate electricity through a chemical reaction and are less polluting than other power generation methods. In this project, a fuel cell is simulated from the PEMFC model.

Desalination

Project number 9 investigates the performance of a solar still thermal desalination unit. The present model consists of a small chamber with a sloping glass surface at the top. The solar heat passes through the glass to the surface of the water in the enclosure and causes surface evaporation (applying a UDF for surface evaporation). The resulting vapor impacts 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.

Decomposition

In project number 10, according to the geometry, the design and grid generation has been done. The combination of DPM (discrete particle method) and species transport methods was used to investigate the decomposition effect of magnesium oxide particles. This reaction is exothermic in the reactor chamber and increases its temperature. From the left inlet, argon gas enters at a temperature of 300 ° C. From the right inlet, argon gas enters at a temperature of 700 ° C with the injection of magnesium oxide particles at the same temperature.
