To Simulate Flow of fluid over a throttle body in converge studio and post-process the results

Aim:- To Simulate Flow of fluid over a throttle body in converge studio and post-process the results

Geometry:- Geometry is taken in .stl format and it was made up in Solidworks.

Meshing:- The Geometry has the base grid size of 0.002 in x,y,z directions with 6000 grid cells(approximately).

Fixed embedding is used with the scale of 2 and layer 4 near the throttle area.

Fluid used:- Air is supposed to flow through the throttle.

Boundary Conditions:-

1) inlet:-

2) outlet:-

3)elbow wall- it is considered as wall

4) throttle - it is considered as wall

Solver Settings:-

1) RNG K-e method is used with default parameter settings.

2) Full hydrodynamic Model is used with pressure based steady solver.

3) it is considered as compressible flow simulation.

Results and Discussion

Convergence graphs

1) Mass flow at oulet

Mass flow inside throttle body

Velocity:-

Density

Pressure:-

There is high-pressure drop below the throttle area which as expected.

The simulation is also tried with the different CFL number (0.5 and 0.2) there was no effect of it on results.
