چکیده مقاله :
In this study, COMSOL Multiphysics is employed to model the transport of textile dye contaminants in a riverine system, with a focus on their dispersion along laminar flow. The objective is to understand the impact of these pollutants on aquatic ecosystems. Initially, the flow in the river is assumed to be in a steady state, facilitating the development of a comprehensive numerical model for contaminant dispersion. Numerical solutions for momentum and mass transfer in the river are derived through MATLAB simulations and compared with simulations obtained through COMSOL Multiphysics to assess the accuracy and reliability of the computational model in replicating real-world scenarios. The parameters used in the COMSOL simulation include geometry and materials, defining the river's structure and properties, as well as physics modules governing momentum and mass transfer. Sensitivity analyses are conducted by varying parameters such as the length and depth of the river to understand their impact on velocity and concentration profiles. Additionally, the modeling of mass transfer for textile dye contaminants reacting with water is investigated, considering carbon dioxide and iron (II) oxide as models of contaminants that react with water. This multifaceted approach aims to provide a thorough understanding of how textile dyes spread and interact in riverine environments, contributing valuable insights for environmental protection and remediation efforts.
