Simulation design of automotive exhaust manifold based on the respiratory system

Combination of bionics principles, according to the structure of the human lung bronchus, the Jetta 2V engine exhaust manifold be biomimetic designed optimization, and use finite element software ANSYS CFD module FLOTRAN to analysis flow field and coupled thermal field for the original exhaust manifold and bionic exhaust manifold., comparing two kinds of exhaust manifold temperature field and flow field, as well as the temperature and speed of outlet airflow. The results showed that the bionic exhaust manifold every pipe flow more evenly, the average temperature is lower than the original exhaust manifold pipe, flow resistance significantly reduced.
