Model & approach
- Define the baseline geometry and permissible design space
- Evaluate the flow field and objective function with CFD
- Use adjoint geometry sensitivities to guide the iteration
Method example / Process engineering
Flow-oriented design of a compact bend
CFD and adjoint optimization were used to develop a compact flow turn within defined packaging constraints.
Engineering question
The flow had to turn within a small space while keeping pressure loss and outlet distribution under design control.
Boundary conditions
- A 90-degree change in flow direction
- Restricted package space and neighboring obstructions
- Pressure loss or mass-flow distribution as possible objectives
Results of the assessment
- The sensitivity field identified the wall regions that most affected the objective.
- Geometry changes could be derived within the defined design space.
- The example documents a method sequence rather than a customer performance claim.
Engineering consequence
The adjoint result guided the shape iteration before detailed engineering development.
Context
The method example provides no absolute operating values or experimental validation.
