Internal combustion engines (IC engines) have been around for centuries transforming the mobility sector as we know it today. The critical problem during the operation of an IC engine is emissions. In the current study, emphasis was given to enhancing the exhaust gas calorimeter through modifications, as a result of which the temperature of hot gases decreases. The modification process was carried out using Creo software, followed by computational fluid dynamics analysis under ANSYS Fluent software. After conducting the analysis and comparing the obtained results, it was concluded that the heat transfer rate is higher in convergent shape exhaust gas calorimeter.

摘要

Internal combustion engines (IC engines) have been around for centuries transforming the mobility sector as we know it today. The critical problem during the operation of an IC engine is emissions. In the current study, emphasis was given to enhancing the exhaust gas calorimeter through modifications, as a result of which the temperature of hot gases decreases. The modification process was carried out using Creo software, followed by computational fluid dynamics analysis under ANSYS Fluent software. After conducting the analysis and comparing the obtained results, it was concluded that the heat transfer rate is higher in convergent shape exhaust gas calorimeter.
