From wind farm yield to turbomachinery stage detail.
From wind farms to high-fidelity turbomachinery simulations across the energy sector. Yield predictions and efficiency guarantees both rest on flow physics that is expensive to measure and cheap to get wrong.
1 · Sector needs with respect to CFD
Revenue and warranty exposure follow directly from predicted performance, so the sector needs simulation resolving atmospheric inflow, wake losses and stage-level machine behaviour with quantified uncertainty.
| REQUIREMENT | WHAT IT DEMANDS OF THE SIMULATION |
|---|---|
| Atmospheric inflow realism | Terrain, roughness, stability and shear reproduced so hub-height wind resource is representative of the site rather than idealised. |
| Wake and array losses | Turbine-to-turbine wake interaction, deep-array effects and blockage, including neighbouring farm influence on yield. |
| Turbomachinery stage accuracy | Blade-row interaction, tip leakage, secondary flows and off-design behaviour resolved for compressors, turbines and pumps. |
| Thermal and combustion coupling | Heat transfer, cooling flows and combustion behaviour where efficiency limits are set by material temperature. |
| Uncertainty quantification | Sensitivity of predictions to inflow, model and geometry assumptions — essential when figures back financial guarantees. |
2 · Typical representative cases
Microscale flow modelling over hills, forests and escarpments to correct mast measurements to turbine positions.
Array wake interaction across the wind rose to quantify losses and improve turbine positioning and yaw strategy.
Blade sectional and full-rotor performance including stall, soiling sensitivity and add-on device gains.
Multi-stage machine performance, surge margin and secondary loss breakdown at design and part-load operation.
Draft tubes, intakes, volutes and pump-turbine passages, including cavitation onset and swirl-induced losses.
Burner mixing, boiler and heat-exchanger flow distribution, emissions trends and cooling-tower plume behaviour.
3 · Policy and standards verifiable through CFD
Simulation supports — and in several frameworks explicitly permits — demonstration of compliance. Acceptance criteria and validation evidence are agreed with you and the approving body before the study begins.
| FRAMEWORK | HOW CFD SUPPORTS VERIFICATION |
|---|---|
| IEC 61400-1 | Wind turbine design requirements. Site-suitability assessment needs turbulence intensity, shear and inflow-angle values at each position — quantities routinely produced by CFD for complex terrain. |
| IEC 61400-12-1 / -12-4 | Power performance measurement. Site calibration and numerical flow-correction of power curves are explicitly supported by flow modelling of the terrain. |
| ASME PTC 10 / PTC 46 | Compressor and plant performance tests. Guarantee testing and correction to reference conditions are supported by machine simulation of the tested operating points. |
| ISO 5801 | Industrial fan performance testing. Installation effects and inlet distortion that penalise measured performance can be diagnosed and corrected before testing. |
| IED 2010/75/EU | Industrial emissions. Combustion and stack dispersion modelling supports permit applications and demonstration of emission and air-quality limits. |
A complete outsourcing solution: an engineering description of your problem, the geometry or area to analyse and the operating flow conditions are enough to start. All work is carried out by CompFlow personnel at company premises under strict bidirectional non-disclosure agreements, on in-house computing facilities including a 120-core cluster.
Engagement is project-based (predefined deliverables and deadlines) or yearly (a set number of consultancy hours). Related services: CFD Consulting · Code Development · Flow Measurements · 3D Design & Scan · CFD Training · CFD Support.
