Week 4.1: Project - Steady state simulation of flow over a throttle body

AIM: To setup and run transient state simulation for flow over a throttle body.

Procedure:

A CAD model is imported to converge studio.

Check for diagnosis abd assign the boundaries to the region.

Case Setup:

• Pressure based transient simulation.
• Inlet pressure = 150000Pa
• Outlet Pressure = 100000Pa
• Outlet Temperature = 300K
• Turbulence model = RNG-E
• Base grid size = 0.002m
• Fixed Embedding
• 

Geometry:

Mesh:

The mesh size is 0.002m.

The embedded details are shown above.

Velocity plot:

Mass flow rate:

Pressure contour:

We can see that the pressure is reduced in the end.

Discussions:

The velocity near thethrottle varies when the flow encounters near the throttle.

The velocity at the outlet decreases and the pressure increases before the valve.
