Thermal Analysis of Exhaust Manifold Coating with High Temperature Resistant Materials
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 12
Abstract
In IC engines exhaust system plays an important role in delivering the waste gases to a safe distance and also it helps in reducing the sound pollution and air pollution ,these exhaust systems ,mainly exhaust manifolds suffer a lot of thermal stress the life of the manifold is much effected due to the exposer with hot flue gases ,sometimes due to emissive heating these manifolds will get blow holes and produce a lot of noise , zirconia based materials exhibits low thermal conductivity, high hardness, and stable fracture toughness compared to other evaluated materials. One material that can be applicable in diesel exhaust application is mullite, which showed similar performance to zirconia based materials. In this study we design a exhaust manifold with different coatings on it and we test it with Finite Element Methodology, but due to design limitations and some messing problem the work is carried forward by assuming complete body with coating material both temperature distribution and thermal stress concentrations are calculated using Finite Element Methodology. For modelling Catia V5 R20 is used and for Finite Element Methodology Ansys 15.0 is used.
