IMPLEMENTING MASS AND SPECIES SINK TERMS IN FLUENT FOR CO2/CH4 SEPARATION IN MEMBRANE MODULE

With rising demands for efficiency and sustainability in industrial processes, computational simulations are key for decision-making. This study examines CO2 separation from CH4, a crucial process for reducing greenhouse gas emissions and improving methane quality, through hollow fiber membrane separation. Using Ansys Fluent, the implementation of a mass sink term in global mass conservation and species conservation equations were evaluated, utilizing both Named Expression and User Defined Function approaches. It has been shown that it is possible to use source terms to emulate membrane mass capture and that no difference has been noticed by using either Named Expressions or UDF.
