Simulation of the Gaseous Species Transport and Combustion of the Methane in the Drop Tube using ANSYS

Abstract

The main goal of the project to study the gaseous species transport and combustion of methane in the drop tube by using ANSYS FLUENT. The problem is divided into three steps such as in first step we are going to do CFD modelling of the air flow without heat transfer in the drop tube. In second step CFD modelling of air flow by gaseous species (O_(2 ),H_2 O,CO_2 AND N_2) without heat transfer in the drop tube. In third step CFD modelling of air flow by gaseous species and combustion of the methane with oxygen in the drop tube. Combustion of methane will be calculating for different models such Finite-rate/tci, Finite-rate /Eddy dissipation, Eddy dissipation and Eddy-dissipation concept. The geometry of drop tube is created in design modeller and mesh is generated in ANSYS meshing which is read to fluent where simulation of the gaseous species and combustion of methane is calculated for different models.
