Flow analysis of separator baffles in a pipe reactor

CFD assessed the form and orientation of separator baffles whose movement through pipe bends could impair stable operation.

CFD result for a pipe bend containing a separator baffle — Process & plant engineering · CFD simulation

Industry: Process & plant engineering
Services: CFD simulation

Engineering question

Separator baffles had to remain suspended in the flow without unwanted rotation or becoming trapped in pipe bends.

Model & approach

Represent the pipe bend and baffle geometry as a 3-D flow domain
Compare incidence, pressure distribution and rotational tendency
Iterate baffle form and orientation

Boundary conditions

Pipe-reactor geometry with bends
Multiple baffle forms and orientations
Fluid data and flow rates from the project model

Results of the assessment

The analysis located flow states associated with rotation or sticking risk.
Pressure and velocity fields explained the fluid forces acting on the baffle.
Geometry and orientation emerged as direct design parameters.

Engineering consequence

The variant study produced a form and orientation recommendation for the modeled pipe system.

Context

The assessment covers fluid forces and the design direction; coupled body motion is outside the scope of this example.
