🎉Happy 2026!🎉
Before we jump into the new year, let's review the posts that closed out 2025...
A Framework for Wind Turbine Noise ReductionAs wind energy expands globally, noise emissions have become a critical factor for regulatory compliance, public acceptance and operational profitability. This article outlines a high-fidelity, multi-disciplinary framework for predicting and mitigating the two primary types of wind turbine noise: broadband aero-acoustic noise from the blades and tonal vibro-acoustic noise from the drivetrain. We present two integrated simulation workflows that enable engineers to design quieter turbines. The aero-acoustic workflow uses fluid simulation to optimize blade serrations, achieving up to 4 dB of noise reduction in key frequencies. The vibro-acoustic workflow models the entire turbine to trace mechanical vibrations from the gearbox to radiating surfaces, such as the tower, identifying the dominant noise paths. We explain how this holistic approach, supported by secure IP-protected collaboration, helps operators reduce costly power curtailments, accelerate certification and improve community relations. | |
How Simulation Accelerates Sustainable Energy InnovationGlobal electricity demand is rising. Low-emission sources like renewables and nuclear power must meet this demand. For engineers, this moment brings pressure to design smarter, cleaner energy systems that can be deployed faster, maintained easily, and deliver consistent, long-term performance. A new engineering workflow is required, one that unites faster decision-making, collaboration, and advanced simulation to validate performance from the first iteration. | |
