Plasma Gasification Reactor CFD Simulation, ANSYS Fluent Training

Description

Description

The present problem simulates the airflow inside a plasma gasification reactor using ANSYS Fluent software.

In general, plasma gasification is a process in which organic materials are converted to synthetic gas with the help of plasma. Arc-ignited plasma is used to ionize and catalyze organic matter into synthetic gas and solid waste.

These operations are commonly used for waste remediation and the evaporation of biomass and hydrocarbons such as coal and petroleum sands.

The present model is designed in two dimensions using Design Modeler software. The model consists of a symmetrical compartment that has two edges as inputs on both sides and one edge at the top as an outlet.

The meshing has been done using ANSYS Meshing software, and the mesh type is structured. The element number is 8711.

Plasma Methodology

Fluid flow enters the chamber from two inlets on either side of the reactor at a velocity of 0.1 m/s and a temperature of 2000 K and exits at the top of the reactor at a pressure equal to atmospheric pressure. Also, the side walls of the reactor have a constant temperature equal to 600 K.

Plasma Conclusion

At the end of the solution process, two-dimensional contours related to pressure, velocity, and temperature, as well as path lines and velocity vectors, are obtained. The pressure decrease when the flow gets close to the outlet.

The maximum velocity occurs in the middle of the device, where the fluid flows from two separated inlets collide. Also, based on the project description, the maximum temperature is located at inlets.
