The present article is focused on the condensation process of exhaust gases to reduce the air pollution to a possible extent. It is accomplished by circulating liquid N2 through copper tubes inside a chamber that is designed to condense the oncoming exhaust gases from the muffler of automobiles, thereby condensing a significant portion of exhaust gases. The condensed gases can be stored and processed at any industrial premises for recycling in a cost-effective manner. The work reported herein compares the design and analysis of two different mechanisms to achieve the effective condensation of automobile exhausts (i.e.)., one involves the employment of copper tubes with Liquid N2, and other involves porous bed kept inside copper tubes with Liquid N2. It is observed that a significant improvement in the heat transfer characteristics of the later version with porous bed over the other counterpart. The modelling and meshing of copper tubes with porous material is a tedious process, because it requires a huge number of nodes to capture the geometry. Hence, the non-equilibrium porous bed module available in the ANSYS Fluent tool is used to carry out the numerical analysis of the entire model. Further, the performance characteristics of the porous bed model are validated with a small sectional model of copper tube with porous bed and by a novel experimental technique involving distilled water in copper tubes. The outcomes of the studies are presented with different colour band metrics and trial experimental results. [ABSTRACT FROM AUTHOR] |
