What it is
Aerodynamic modeling predicts how air moves through and around a design: velocity and pressure distributions, flow separation and recirculation, pressure drop, and the uniformity of flow arriving at fans, heat sinks and openings.
For many products, the airflow is the root of both the performance question and the noise question. A flow path that separates, accelerates through a restriction or delivers distorted inflow to a fan tends to cost efficiency and generate noise at the same time — so the two are best evaluated together.
Problems it helps solve
- Insufficient airflow or higher-than-expected pressure drop
- Non-uniform or distorted inflow into fans and blowers
- Separation, recirculation or jets near grilles, vents and obstructions
- Local high-velocity regions that are likely to drive noise
- Choosing between duct, inlet, outlet or baffle geometries
When to use it
- When layout or packaging decisions will fix the airflow path
- Before tooling ducts, housings or enclosures
- When performance and noise targets have to be balanced
- As the first stage of an aeroacoustics study that depends on a trustworthy flow field
Typical engineering inputs
- 3-D geometry of the flow path (CAD preferred)
- Operating conditions: flow rate or fan operating point, speeds and temperatures as relevant
- Fan or component performance data where available
- Performance requirements: flow, pressure drop, velocity limits
Early-stage or incomplete inputs are normal — scoping establishes what is actually needed. Proprietary geometry is shared only after first contact, by a method agreed with you.
How SH Consulting approaches it
- Identify what matters. Define the flow path and the quantities the decision depends on.
- Prepare the geometry. Simplify CAD appropriately while keeping the features that control the flow.
- Set up the simulation. Mesh and apply boundary conditions — steady or unsteady, depending on the question.
- Solve and verify. Check sensitivity and sanity against data or hand calculations before trusting the result.
- Compare and explain. Evaluate variants and explain the implications for performance and noise.
Outputs
