Transient Thermal Simulation Process over a Diesel Exhaust System during Regeneration 2011-01-0658
With the constant need to meet new environmental regulations, the improvement of automotive exhaust systems technologies to be cleaner and more effective is a necessity.
To achieve these regulations the automakers have been focused on the development of better particle filters and more effective cleaning processes.
Catalyst Oxidation and Diesel Particle Filter Regeneration are good and effective techniques to accomplish these objectives but the amount of heat generated by these processes is a concern in the thermal management of the vehicle.
To gain a better understanding of these effects Finite Element Thermal Analysis has proved to be a useful tool to predict and observe the increment of temperature during these processes.
This work is focus on a simulation process using several 1-D and 3-D techniques to predict the skin exhaust temperature during the regeneration process moment in which the system achieve the maximum temperature.
The objective of this work is to assess the simulation results and compare it to physical test results in order to correlate the proposed methodology.
