ABSTRACT
Underground Coal Gasification is a non-traditional, in situ combustion process for converting coal into product gases. In this process, coal is combusted and the produced syngas which basically contains CO2, H2, CO and CH4 is extracted to the surface with the help of drilled wells. In this study, with reference to a lab-scaled UCG experiment and taking the experimental data as the basis for the research, a two-dimensional computational fluid dynamics (CFD) reactor model was created and further studies were done to establish the activity at the different locations of the reactor. The Mass Imbalance, Discrete Phase Variables, Velocity, Turbulent Kinetic Energy, Strain Rate, Mesh-Contour Diagrams along with the Scaled Residual Plot were obtained to give the reader an extensive knowledge about the process and simulation. The CFD model results obtained in our study were compared with the experimental data from the above citing to validate our obtained model and its results.
