Modeling And Simulation of Gas Flow Velocity In Catalytic Converter With Porous
نویسنده
چکیده
Stringent emission regulations around the world necessitate the use of high-efficiency catalytic converters in vehicle exhaust systems. Experimental studies are more expensive than computational studies. Also using computational techniques allows one to obtain all the required data for the Catalytic Converter, some of which could not be measured. In the present work, Geometric modeling ceramic monolith substrate with square shaped channel type of Catalytic converter and coated platinum and palladium using fluent software. In this software we are using crate inlet-outlet flanges and housing of the catalytic converter. After design of modeling us done different parameters in Fluent Preprocess like Analysis Type, Domain Type etc. This project studies the different porosity of porous medium how to affect to flow pressure field under the conditions of same inlet velocity and ceramic diameter by CFD method. Geometric model of the catalytic converter has been establish and meshed by the pre-processing tool of FLUENT. The flow pressure simulation filled contours and curve of center line static pressure distribution of the ceramic porous material show that in the case of other conditions remain unchanged, the less the porosity of the ceramic porous material, the higher the inlet pressure and the more the pressure loss of the porous material. The more Porosity of ceramic is beneficial to exhaust catalytic converter.
