Week 4: Project - Steady state simulation of flow over a throttle body

AIM: To perform steady state simulation for flow over a throttle body.

PROCEDURE:

• The throttle body geometry is imported and the boundary flagging is done.

• Once the boundaries are allotted then we proceed for the case setup.

Setup:

• Material - Air
• Species - N2 and O2
• Run parameters

• Simulation parameters

• Grid size of 0.002m is used and for the sake of local refinement, embedding is also done to the geometry.

Results:

Now the above case is run in cygwin and once the simulation is completed,the results are post processed in paraview and the solution plots are obtained in converge studio.
